Author is An, Ju Hyeon; Kim, Kyu Dong; Lee, Jun Hee.

A highly chemoselective room-temperature deoxygenation method applicable to various functionalized N-heterocyclic N-oxides via visible light-mediated metallaphotoredox catalysis using Hantzsch esters as the sole stoichiometric reductant to afford deoxygenated N-heterocycles I [R = 6-OMe, 6-Cl, 2-Ph, etc.], II [R1 = H, 5-Br; X = CH, N] and III [R2 = 3-Ph, 2,6-Cl2, pyridin-2-yl, etc.] were reported. Despite the feasibility of catalyst-free conditions, most of these deoxygenations could be completed within a few minutes using only a tiny amount of a catalyst. This technol. also allowed for multigram-scale reactions even with an extremely low catalyst loading of 0.01 mol %. The scope of this scalable and operationally convenient protocol encompassed a wide range of functional groups, such as amides, carbamates, esters, ketones, nitrile groups, nitro groups and halogens, which provided access to the corresponding compounds I, II and III in good to excellent yields (an average of an 86.8% yield for a total of 45 examples).

Abstract: The condensation reaction of mono-amido-functionalized pillar[5]arenes with tere- and iso-phthaloyl diisothiocyanates in acetone under ultrasonic irradiation afforded tere- and iso-phthaloylthiourea-bridged dipillar[5]arenes. The similar reaction of mono-amido-functionalized pillar[5]arenes with 1,ω-bis(4-isothiocyanatophenoxy)alkanes also afforded diphenoxyalkylene thiourea-bridged dipillar[5]arenes. 1H NMR and NOESY spectra clearly indicated that bis-[1]rotaxanes were formed by insertion of longer alkylene chains into the cavities of two pillar[5]arenes. On the other hand, the free-forms of dipillar[5]arenes were obtained with the shorter ethylene chains existing on the outside of the cavities of two pillar[5]arenes.

The aggregation of the mixture of anionic surfactant – sodium dodecyl sulfate (SDS), and an anionic dye – bromocresol green sodium salt (BCG) was investigated by conductometric technique in water and alc./diolic media within a temperature range of 300.55-320.55 K (with 5 K interval). The observed critical micelle concentration (cmc) decreases with surging of the concentration of BCG, following the same trend for β value. In presence of additives (ethanol, propanol, and ethylene glycol), the cmc value decreases up to a certain concentration and then the cmc values start enhancing with increasing concentration in all the cases. With the increased additive percentage, the β values continually decrease. Again, the cmc value increases gradually with the increase of temperature both in water and aqueous additives media. The free energy of studied aggregation phenomena is neg. which experiences an augmentation with the escalation of temperature The increased neg. value of free energy at elevated temperature indicates that the process becomes more spontaneous at a higher temperature The and ΔH0m and ΔS0m values reveal that the probable interaction forces between BCG and SDS are hydrophobic, ion-ion, as well as electrostatic interactions.

A combination of reaction partners that function as a chiral interlocking auxiliary to both orientate a macrocycle and effectively, load it onto a new axle was discovered. These substrates was used to demonstrate the potential of a chiral interlocking auxiliary strategy for the synthesis of mech. planar chiral rotaxanes by producing a range of examples with high enantiopurity (93-99% e.e.), including so-called ′impossible′ rotaxanes whose axles lack any functional groups that would allow their direct synthesis by other means. Intriguingly, by varying the order of bond-forming steps, can effectively choose which end of an axle the macrocycle is loaded onto, enabling the synthesis of both hands of a single target using the same reactions and building blocks.
