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.

An optically active monophosphino carboxylic acid derivative of formula (I):
wherein:
each R1 independently represents a C1-6 alkyl group or phenyl group which is unsubstituted or substituted with a C1-4 alkyl group or C1-4 alkoxy group;
R2 represents a C1-4 alkyl group; and
R3 and R4 each independently represents a hydrogen atom, or a C1-4 alkyl group or phenyl group which is unsubstituted or substituted with a C1-4 alkyl or C1-4 alkoxy group.
