Methyl (R)-glycidate (=methyl (R)-oxiranecarboxylate; 2) in superacidic trifluoromethanesulfonicacid medium reacts with electron-rich arenes to give α-hydroxy-β-arylpropanoate derivatives 3a–3f with high stereospecificity. At the same time, the observed high regioselectivity has been attributed to superelectrophilic activation of the glycidate.
