Abstract
NEW MATERIAL:A compound of formula I. USE:It is used to prepare pyrenophorin, a 16-membered macrolide antibiotic. PREPARATION:A lactol derivative of formula II is allowed to react with diisopropyl methoxycarbonylmethylphosphonate in the presence of 4- dimethylaminopyridine to give the compound of formula I. The amount of 4-dimethylaminopyridine used is 10-50mol.% based on the lactol derivative, and the reaction temperature and time are preferably at 100-150 deg.C and for about 10-150hr.
