Intramolecular acryloxypalladation. Stereospecific synthesis of ring fused unsaturated α-methylene γ-butyrolactones
摘要:
The intramolecular carboxypalladation reaction [Pd(OAc)(2) 5 mol% NaOAc 2 eq, O-2, THF, rt] of 2-(2-Cycloalken-1-yle) propenoic acids yields ring fused alpha-methylene gamma-butyrolactones with good yields (75-80%). (C) 1997, Published by Elsevier Science Ltd.
