Abstract
Abstract The direct oxidation of bis-methylthioethers 1 by t-butyl hydroperoxide, titanium tetra- iso-propilate and (+)-diethyltartrate, affords the almost enantiomerically pure dl bis- methylsulfinylbenzenes 2 (ee⩾ 99%) in a process which is also characterized by a very high diastereoselectivity.
