Biomimetic Total Synthesis of Dysoxylum Alkaloids

A five-step total synthesis of Dysoxylum alkaloids has been achieved using a biomimetic approach from zanthoxylamide protoalkaloids. The synthesis featured a direct amidation and a Bischler-Napieralski reaction to form the dihydroisoquinoline ring, which

Asymmetric hydrogenation of cyclic imines with an ionic Cp*Rh(III) catalyst

When associated with a noncoordinating bulky counteranion, a cationic Cp*Rh(III)-diamine catalyst displayed excellent enantioselectivities in asymmetric hydrogenation of cyclic imines, affording bioactive tetrahydroisoquinolines and tetrahydro-β-carboline

Asymmetric synthesis of (s)-norlaudanosine and (s)-tetrahydrohomopapaverine by catalytic asymmetric hydrogenation with chiral diphosphine-iridium(i)-phthalimide complex catalysts

Optically active 1,2,3,4-tetrahydroisoquinoline alkaloids, (S)-norlaudanosine and (S)-tetrahydrohomopapaverine, were prepared by catalytic asymmetric hydrogenation of 1-substituted 3,4-dihydro-6,7-dimethoxyisoquinolines with 1 mol % of an iridium(I) compl
