The development of an efficient synthesis of the erythrinaalkaloid 3‐demethoxyerythratidinone is described. A titanium(III) catalyzed umpolung in form of an imine–nitrile coupling reaction serves as key step for the construction of the highlighted C–C bond.

identified a novel series of disubstituted benzamide compounds with significant activity against malaria strains 3D7 and K1. These compounds represent a new antimalarial molecular scaffold exemplified by compound 1, which demonstrated EC50 values of 60 and 430 nM against strains 3D7 and K1, respectively. Herein we report our findings on the efficient synthesis, structure–activityrelationships, and biological

Bu3SnH-mediated radical translocation/cyclization reactions of 1-alkynyl-2-(o-iodobenzoyl)tetrahydroisoquinolines were examined. The 1-[3-(trimethylsilyl)prop-2-ynyl]- (10a) and 1-[4-(trimethylsilyl)but-3-ynyl]-1,2,3,4-tetrahydroisoquinoline derivatives (10b), with Bu3SnH in the presence of azobis(isobutyronitrile) in boiling toluene, gave regioselectively the 6,7,8,9-tetrahydro-5H-benzocyclohepten-5,8-imine (12a) and 5,6,7,8,9,10-hexahydrobenzocycloocten-5,9-imine (12b), respectively.
