regioselective ring-opening reaction of epoxides with various carboxylicacids under metal-free conditions is reported. The ring-opening of epoxides takes place in the presence of graphite oxide as an efficient and available catalyst to produce the corresponding 2-hydroxy monoester and 1,2-diester derivatives in good yields. Regioselective attack of the nucleophile, short reaction times, metal-free conditions
A novel and highly efficient procedure for insideselective esterification of terminal vic-diols has been achieved in one-pot via Yb(OTf)3-catalyzed formation and partial hydrolysis of cyclic orthoesters. This method offers several advantages including wide compatibility with acid labile functional groups, and good to high regioselectivity and yields.
