I found the field of Chemistry very interesting. Saw the article Gold- or Indium-Catalyzed Cross-Coupling of Bromoalkynes with Allylsilanes through a Concealed Rearrangement published in 2019.0. Formula: C7H6O2, Reprint Addresses Echavarren, AM (corresponding author), Barcelona Inst Sci & Technol, Inst Chem Res Catalonia ICIQ, Ave Paisos Catalans 16, Tarragona 43007, Spain.; Echavarren, AM (corresponding author), Univ Rovira & Virgili, Dept Quim Analit & Quim Organ, C Marcelli Domingo S-N, E-43007 Tarragona, Spain.. The CAS is 100-83-4. Through research, I have a further understanding and discovery of 3-Hydroxybenzaldehyde

The gold(I)-catalyzed reaction of bromoalkynes with allylsilanes gives 1,4-enynes in a formal cross-coupling reaction. Mechanistic studies revealed the involvement of gold(I) vinylidenes or vinylidenephenonium gold(I) cations depending on the substituent on the bromoalkyne. In the case of bromo arylalkynes, the vinylidenephenonium gold(I) cations lead to 1,4-enynes via a 1,2-aryl rearrangement. The same reactivity has been observed in the presence of InBr3.

The first defluorinative ipso-functionalization reaction of (trifluoromethyl)alkenes is reported. This exclusively regioselective ipso-defluorooxylation of (trifluoromethyl)alkenes with oximes affords various attractive O-(1,1-difluoroallyl)oxime ethers efficiently via a chemoselective single C(sp(3))-F bond activation in the CF3 group. Primary mechanism studies indicated an anionic S(N)2-type substitution pathway might be involved in this transformation.

A sustainable boron-based catalytic approach for chemoselective N-alkylation of primary and secondary aromatic amines and amides with primary, secondary, and tertiary benzylic alcohols has been presented. The metal-free protocol operates at low catalyst loading, tolerates several functional groups, and generates H2O as the sole byproduct. Preliminary mechanistic studies were performed to demonstrate the crucial role of boron catalyst for the activation of the intermediate dibenzyl ether and to identify the rate-determining step.

The synthesis of aminocarbonyl derivatives as biologically active compounds by using polyethylene glycol (PEG-400)-SO3H-coated Fe2O3 is reported. The heterogeneous nanocatalyst was prepared via in-situ co-precipitation method and its structure and morphology was characterized by Fourier-transform infrared spectroscopy, energy-dispersive X-ray analysis, X-ray diffraction pattern, field-emission scanning electron microscopy image, vibrating sample magnetometer curves, N-2 adsorption-desorption isotherm and inductively-coupled plasma analysis. Noteworthy, the green composite nanocatalyst was applied for the one-pot multicomponent synthesis of aminocarbonyl compounds at room temperature. This work had advantages such as significant nanocatalyst activity, recoverability, short process time, mild reaction conditions and high products yields.

Weakly coordinating, ketone-directed C-H vinylation using vinyl acetate is reported here for a wide range of aromatic ketones such as acetophenones, diaryl ketones, chromones and biologically relevant chalcones under cost-effective and air-stable cobalt(iii)-catalysis. Regioselective, mono-vinylation occurs for challenging vinyl substitution-free styrenes in moderate to good yields, and this moiety has been used to synthesize functionalized indanone, alpha-naphthol and an advanced intermediate for bruguierol A synthesis. An acrylate-surrogate provided the corresponding alkenylated product under these vinylation conditions. Detailed mechanistic studies are carried out to support the proposed catalytic cycle.

Lantana camara (L.) is employed by several ethnical groups to treat numerous diseases. Although there are no ethnomedical reports on its use against leishmaniasis, organic extracts prepared from L. camara were shown to display leishmanicidal activity. In the present study, we carried out a bioassay-guided fractionation of the dichloromethane extract from Mexican L. camara in order to identify the compounds responsible for the leishmanicidal activity. Eighteen chromatographic fractions (FI-FXVIII) were evaluated in vitro against Leishmania mexicana and L. amazonensis. FII, FX, FXI, FXV, and FXVI showed significant activity against both Leishmania strains, the most potent of which was FXV. Eicosane (1), squalene (2), -ionone (3), caryophyllene oxide (4), -caryophyllene (5), hexanoic acid (6), tiglic acid (7), a mixture of lantanilic (8) and camaric (9) acids, and lantadene B (10) were identified and obtained from the active fractions and evaluated for their leishmanicidal activity. The mixture of lantanilic (8) and camaric (9) acids (79%/21%) was the most potent one (half maximal inhibitory concentration (IC50) = 12.02 +/- 0.36 M). This study indicates that this cultivar of L. camara has high potential for the development of phytomedicines or as a source of natural products, which might represent lead compounds for the design of new drugs against leishmaniasis.

A novel methodology for the preparation of trideuterovinyl derivatives of high purity directly from alcohols, thiols, and NH-compounds was developed. Commercially available calcium carbide and D2O acted as a D-2-acetylene source, and DMSO-d(6)was used to complete the formation of the D2C=C(D)-X fragment (X = O, S, N). Polymerization of a selected trideuterovinylated compound showed a very promising potential of these substances in the synthesis of labeled polymeric materials. Biological activity of the synthesized trideuterovinyl derivatives was evaluated and the results indicated a significant increase of cytotoxicity upon deuteration.

A visible-light-induced carbonylation of indoles with phenols for the synthesis of indole-3-carboxylates has been developed. The reaction proceeded via a radical carbonylation process in which elementary I-2 was used as an effective photosensitive initiator and, thus, avoided the use of transition metal catalysts. A series of different aryl indole-3-carboxylates were prepared in moderate to good yields. The broad applicability of this methodology was further highlighted by the late-stage functionalization of several phenol-containing natural products and pharmaceuticals.
