Kinetic resolution of indolines through reductive amination of aldehydes by chiral Br¡ãnsted acid

We have developed a highly efficient and practical strategy for the kinetic resolution of indoline derivatives, involving a chiral Br¡ãnsted acid-catalyzed iminium ion formation and asymmetric transfer hydrogenation cascade process. The kinetic resolution allows the synthesis of 2-substituted N-benzylindolines in good yields with moderate to excellent enantioselectivities.

Metal-, Photocatalyst-, and Light-Free Minisci C-H Alkylation of N-Heteroarenes with Oxalates

Herein, we report a mild protocol for metal-, photocatalyst-, and light-free Minisci C-H alkylation reactions of N-heteroarenes with alkyl oxalates derived from primary, secondary, and tertiary alcohols. The protocol uses environmentally benign persulfate as a stoichiometric oxidant and does not require high temperatures or large excesses of either of the substrates, making the procedure suitable for late-stage C-H alkylation of complex molecules. Notably, several pharmaceuticals and natural products could be functionalized or prepared with this protocol, thus demonstrating its utility.

Photoreactions in Crystals with Ethenes: Selectivities and Crystal Engineering

Photoreactions in crystals of sterically hindered dimethylenecyclopentanones 1 and trimethylenecyclopentanes 4 lead to E/Z isomerizations and 1,5-H shifts.The stereochemical result of the photodimerization in the crystalline state of the heterostilbenes 6 is apparently determined by the polarity (dipole moment), which governs the crystal packing as well.A strong dissymmetry of charge (as in 6a-g) gives rise to H(ead)/T(ail)-syn dimers 7.This correlates well with the molecular stacking in the crystals of 6c, as determined by X-ray analysis.A low dissymmetry of charge (as in 6h) leaves the crystals photostable.At medium polarity two products with H/T-syn and H/H-syn stereochemistry (7 and 8) or, in particular cases, only dimers of type 8 are formed.The precise stereochemistry is proved by comparison with the analyzed 1H-NMR parameters of esters of truxillic and truxinic acids.Bifunctional heterostilbenes like 12c are photostable in the crystalline state.However, strongly polar methoxycarbonyl (13) and acetyl groups (17, 21) lead to photoreactive crystals again.In the case of 17 this is also shown by X-ray analysis.Due to well-defined possibilities of movement, there are three products formed in terms of multiproduct topochemistry. 13 and 21 also form several products upon photoreaction in the crystal.
