Abstract
The asymmetric [2+2]cycloadditions of chlorosulfonyl isocyanate to vinyl et hers derived from sugars and hydroxy acids are presented. The account focus es on various aspects of the cycloaddition and on the transformations of th e resulting [2+2]cycloadducts into clavams and 1-oxacephams. In order to ra tionalize the results of direction and magnitude of [2+2]cycloaddition, the stereochemical models of this reaction are discussed.
