SUBSTITUTED ISOXAZOLIDINES AND ISOXAZOLINES AS INTERMEDIATES FOR DELMOPINOL AND PREPARATION OF DELMOPINOL USING THESE INTERMEDIATES

摘要

The invention concerns a new process for preparing delmopinol using intermediates having formula (A) wherein R is 2-propylpentyl optionally with one, two or three internal unsaturated bonds, or 2-substituted-2-propylpentyl optionally with one or two internal unsaturated bonds wherein the 2-substituent is a leaving group.
