Conjugate intra- and intermolecular addition mediated by methoxide anion on polymeric support
摘要:
By treatment with methoxide anion on polymeric support (IRA 900), chiral beta -oxo or beta -sulphonylamides 2 bearing an alpha,beta -unsaturated ester gave 3,4-disubstituted pyrrolidin-2-ones 3 as easily separable diastereomeric mixtures in good yield and moderate-to-good stereoselection. The polymeric reagent was also effective in promoting both intermolecular conjugate addition and alkylation reactions. (C) 2000 Published by Elsevier Science Ltd.
