Abstract: | A simple and mild procedure was developed for the first time for the C(3)‐selective ring opening of an aromatic 2,3‐epoxy alcohol, i.e., of trans‐3‐phenyloxirane‐2‐methanol ( 1 ), with sodium phenoxides or thiophenoxides (=benzenethiolates) 2 supported by β‐cyclodextrin in H2O at 50° to afford the corresponding 3‐(aryloxy)‐ or 3‐(arylthio)propane1,2‐diols 3 in excellent yields (Scheme, Table). |
