Abstract

Oxathiole derivatives R 0250Ytterbium (III) Triflate Catalyzed [3 + 2] Cycloaddition Involving Isothiocyanates and Epichlorohydrin. -(1,3-Oxathiolan-2-ylidene)anilines are obtained in a highly regioselective cycloaddition of various substituted isothiocyanates and epichlorohydrin. The configuration at the chiral centres of the epoxides is retained. -(XIE, Y.; CHEN, X.; SU*, W.; J. Chem. Res. 2009, 2, 129-132; Coll. Pharm. Sci., Zhejiang Univ. Technol., Hangzhou 310014, Peop.
