The synthesis of the two 7,8-epoxides of carvone has been attained using organocatalysis in a two-step synthetic route through a bromoester intermediate. Among the different reaction conditions tested for the bromination reaction, moderate yields and dias... see more

The diphenyl sulfoxide-catalyzed conversion of aldehydes to 1,1-dichlorides is reported. The reaction proceeds via a sulfurous (IV)-catalysis manifold in which diphenyl sulfoxide turnover is achieved using oxalyl chloride as a consumable reagent.

The catalytic system of triphenylphosphine oxide and phthaloyl dichloride catalysing conversion of aldehydes to 1,1-dichlorides is reported. The reaction proceeds via a P (V) catalysis manifold in which triphenylphosphine oxide turnover is achieved using ... see more

Thiosquaramides are the thio analogues of squaramides that are widely applicable in the fields of asymmetric catalysis, pharmaceutical research, and chemical biology. Having four-membered ring system derived from squaric acid, thiosquaramides are feasible... see more

New methods for efficient preparation of optically active compounds developed recently are reported. Combination of selective organometallic, organocatalytic, phase transfer catalytic and catalytic hydrogenation reactions provided numerousnew optically ac... see more

Fostering research in fundamental organic transformations is of utmost importance for the development of science.[...]

The enantioselective α-amination of 1,3-dicarbonyl compounds has been performed using deep eutectic solvents (DES) as a reaction media and chiral 2-amino benzimidazole-derived compounds as a catalytic system. With this procedure, the use of toxic vo... see more

A highly enantioselective organocatalytic Wolff rearrangement–amidation–Michael–hemiaminalization stepwise reaction is described involving a cyclic 2-diazo-1,3-diketone, primary amine and a,ß-unsaturated aldehyde. Product stereocontrol can be achieved by ... see more

A novel fluorous hydrazine-1,2-bis(carbothioate) was prepared. It showed good catalytic activity in the synthesis of ?-chloroethers with N-chlorosuccinimide under mild reaction conditions. This fluorous organocatalyst could be recovered and recycled sever... see more
