NEW MATERIAL:The compound of formula I. USE:Useful for the production of pyrenophyrin which is a 16-membered ring macrolide antibiotic substance. PREPARATION:The compound of formula I can be produced by reacting a tosylate derivative of formula II with lithium aluminum hydride. The reaction is preferably carried out in an inert solvent (e.g. dichloromethane, chloroform or benzene) at 0-40 deg.C for 30min-6hr. The tosylate derivative of formula II used as a starting raw material can be easily produced by reacting a compound of formula III with p-toluenesulfonic acid chloride.
