Proton-catalysed E-Z isomerisation and Pd(II) assisted carboncarbon cleavage on 3-phenyl-4-(2,4,6-trimethoxyphenyl)methyleneisoxazolin-5-one
摘要:
Proton electrophilic addition to 3-phenyl-4-(2,4,6-trimethoxyphenyl)methyleneisoxazolin-5-one can either catalyse E-Z isomerisation or a Pd(II) assisted cleavage of the exocyclic sp(2)-hybridised C-C bond in dependence on the proton site attack. (C) 2002 Elsevier Science Ltd. All rights reserved.
