Abstract

Abstract Two new protecting groups viz. p??phenyl diphenylmethanol (PDPM) and p?? phenylphenyl diphenylmethanol (PPDPM) were prepared and utilized along with p??methoxy diphenylmethanol (MDPM), for the protection of alcohols in the presence of Yb (OTf) 3. Deprotection of the above ethers was achieved using DDQ or CF3COOH.# IICT Communication Number: 021001.
