One important theme in organic synthesis is to accomplish highly selective transformations under mild conditions, which yield only desirable products. During the past two decades, we have developed several useful tools to achieve this, i.e., organoch

Carbonyls and acetals are converted to 1,3-dithianes and -dithiolanes upon treatment with 2-stanna-1,3-dithianes and -dithiolanes under catalysis by organotin triflates. In these competition reactions, various types of carbonyls and acetals are diffe

1, n -Diol diacetates (n = 2,3,4) are selectively converted into the corresponding monoacetates by distannoxane-catalyzed transesterification. Such unique selectivity is not encountered with 1, n -diol diacetates where n ≥ 5. A great difference in

The mechanism of the Mukaiyama reaction has never been examined from the standpoint of electron transfer. We conclude here that the Lewis mediated electron transfer from hindered ketene silyl acetals to α-enones plays an essential role in connecting
