The invention discloses a method for preparing an indole phosphonate derivative. The method specifically includes: dissolving an indole derivative, organic phosphonic compound, magnesium nitride, molecular sieve and silver carbonate of a catalytic amount into a solvent; reacting at 50-70 DEG C to obtain the indole phosphonate derivative. The indole derivative is used as a, so that raw materials are easy to get and various in type; a product obtained by the method is diverse in type, can be used directly and can also be used for other further reaction. Silver carbonate is adopted as a catalyst, and an organic ligand is not needed, so that cost is lowered, an pollution is reduced. In addition, the method is mild in reaction condition, simple in reaction operation and aftertreatment process, high in yield and suitable for large-scale production.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Related Products of 16732-57-3, you can also check out more blogs about16732-57-3

19F MRI is valuable for in vivo imaging due to the only trace amounts of fluorine in biological systems. Because of the low sensitivity of MRI however, designing new fluorochemicals remains a significant challenge for achieving sufficient 19F signal. Here, we describe a new class of high-signal, water-soluble fluorochemicals as 19F MRI imaging agents. A polyamide backbone is used for tuning the proteolytic stability to avoid retention within the body, which is a limitation of current state-of-the-art perfluorochemicals. We show that unstructured peptides containing alternating N-?-trifluoroacetyllysine and lysine provide a degenerate 19F NMR signal. 19F MRI phantom images provide sufficient contrast at micromolar concentrations, showing promise for eventual clinical applications. Finally, the degenerate high signal characteristics were retained when conjugated to a large protein, indicating potential for in vivo targeting applications, including molecular imaging and cell tracking.

An efficient, unified approach for the synthesis of beta-carbolines, gamma-carbolines, and other fused azaheteroaromatics has been realized under metal-free conditions, from propargylic amines and (hetero)aromatic aldehydes. This unified strategy provides beta- and gamma-carbolines as well as a range of fused azaheteroaromatics with a broad substrate scope and excellent functional group compatibility. The formal synthesis of oxopropalines D and G has been achieved on gram scale (3a), in a one-pot reaction from commercially available materials (previous shortest reported route to 3a was 5 steps). NMR studies of the conversion of imine intermediate 3aa to beta-carboline 3a were conducted and revealed that the reaction proceeded through an allene intermediate.

Dye-sensitized photooxygenations of cyclic and acyclic 1,4-diaza-1,3-butadienes (alpha-Diimines), carrying a methyl or an ethyl group in the 2-position, yield isonitriles and amides, as well as formaldehyde or acetaldehyde.Thus, cyclic alpha-diimines such as 5,6-dimethyl- (1a), 5-methyl-6-phenyl- (1b), 5-methyl-6-(p-tolyl)- (1c), and 5,6-diethyl-2,3-dihydropyrazine (1d) yield the respective 1-isocyano-2-(acylamino)ethanes 2a-d, whereas 5-isopropyl-6-phenyl- (1e) and 5,6-diphenyl-2,3-dihydropyrazine (1f) are inert toward photooxygenation.Acyclic alpha-diimines such as 1,8-bis(acetylamino)-3,6-diaza-4,5-dimethyl-3,5-octadiene (4a), 2,5-diaza-3,4-dimethyl-2,4-hexadiene (4b), 1,4-diaza-2,3-dimethyl-1,4-diphenyl-1,3-butadiene (4c), and N,N’-bis<(1S,2S,3S,5R)-pinan-3-ylmethyl>-2,3-butanediimine (4d) afford the respective isonitriles 5a-d and acetamides 6a-d.With retention of configuration, chiral alpha-diimines such as (-)-N,N’-bis<(S)-1-phenylethyl>-2,3-butanediimine <(S,S)-4e> and its R,R enantiomer <(R,R)-4e>, and (3S,8S)-(-)-3,8-dicarbomethoxy-4,7-diaza-2,5,6,9-tetramethyl-4,6-decadiene <(S,S)-4f> yield the corresponding enantiomerically pure isonitriles (S)-5e, (R)-5e, and (S)-5f and acetamides (S)-6e, (R)-6e, and (S)-6f.Evidence for a singlet oxygen reaction is presented.A working hypothesis is proposed which includes the formation of a transient hydroperoxide 7 that fragments into an isonitrile molecule, an aldehyde, and an N-alkyl- or N-arylnitrilium cation and a hydroxide ion; the latter combine to yield the amide groups in 2a-d and the amide compounds 6a-f.
