Natural product synthesis carbopalladation

Link JT (2002) Synthesis of Natural Products via Carbopalladation. In Negishi E, de Meijere A (eds) Handbook of Organopalladium Chemistry for Organic Synthesis. Wiley, New York, p 1523... [Pg.45]

Medium sized rings can also be efficiently assembled by carbopalladation reactions. An example from natural product synthesis is the construction of several Amaryllida-cae alkaloids including (-)-pancracine Treatment of aryl bromide 140 with... [Pg.1543]

Asymmetric intramolecular carbopalladation is an effective reaction for producing enantioenriched polycycles. Most examples are intramolecular Heck reactions. One seminal example from natural product synthesis is the 5-exo carbopalladation of eneamide 201 to oxindole 202 (after acid treaunent) from a total synthesis of ( )-physostigmine 203 (Scheme The reaction occurs in 84% yield with 95% ee,... [Pg.1553]
