Abstract
Ti-TADDOL catalysts provide good reactivity and moderate enantioselect ivity in the asymmetric [2+2] cycloaddition of silyl ketenes and aldeh ydes. The effects of potential bidentate chelation of benzyloxy substi tuted aldehydes and of the steric size of the ketene silyl group were studied. (C) 1998 Elsevier Science Ltd. All rights reserved.
