chiral auxiliary mediated pictet spengler reactions asymmetric syntheses of laudanosine glaucine and xylopinine
Tetrahedron, 1997Co-Authors: Daniel L. Comins, Paresh M Thakker, Matthew F Baevsky, Mohamed M BadawiAbstract:Abstract Cyclohexyl-based chiral auxiliaries can be used effectively in an asymmetric Pictet-Spengler Synthesis of tetrahydroisoquinoline, aporphine and protoberbine alkaloids. Using this strategy, concise asymmetric syntheses of (−)-laudanosine, (+)-glaucine and (+)-xylopinine have been accomplished.

An Alternative Synthesis Of 1,2,3,4-tetrahydro-9h-pyrido-[3,4-b]-indole [uma Síntese Alternativa Para O (± )-1,2,3,4-tetraidro-{9h-pirido-[3,4-b]}-indol]
2015Co-Authors: De Oliveira A.j.b., Koike L.Abstract:The 1,2,3,4-tetrahydro-9H-pyrido-[3,4-b]-indole, a compound with tranquillizing properties, was prepared in 16% overall yield from the 3-indole-acetaldehyde and tryptamine by applying the classical Pictet-Spengler condensation. Physical and spectroscopic data for such compound are presented.393259264Cox, E.D., Cook, J.M., The Pictet-Spengler condensation: A new direction for an old reaction (1995) Chem.
