Two novel diterpenoids, cassiabudanols A (1) and B (2), were isolated from cassia buds. Their structures were determined by comprehensive spectroscopic analysis and single-crystal X-ray diffraction. Compounds 1 and 2 possess an unprecedented 11,14- c

An organocatalytic highly enantioselective Michael-aldol cascade access to valuable chiral dihydronaphthalenes has been realized. Notably, the strategy via activation of nucleophilic alkyl chains by introducing nitro, chloro, or CF3 group(s) at the o

An efficient bifunctional cinchona alkaloid derived thiourea-promoted enantioselective conjugate addition of nitroalkanes to indolylidenecyanoacetates has been developed under neat conditions. The process leads to synthetically interesting densely fu

A highly enantioselective conjugate addition of nitroalkanes to enones has been developed. The process is efficiently catalyzed by a simple chiral cyclohexanediamine-derived primary amine thiourea with a broad substrate scope.
