The utility of the Pictet–Spenglercondensation of (R)-(+)-glyceraldehyde with dopamine hydrochloride in the enantioselectivesynthesis of isoquinoline alkaloids is demonstrated by the preparation of (S)-(−)-carnegine, (R)-(−)-calycotomine, and (S)-(+)-laudanosine.
Pictet-Spengler Reaction of Biogenic Amines with (2R)-N-Glyoxyloylbornane-10,2-sultam. Enantioselective Synthesis of (S)-(+)-N-Methylcalycotomine and (R)-(+)-Xylopinine
