Chelation and non-chelation controlled stereoselective reduction of a-methoxy-a-phenylthio ketones
摘要:
A series of a-methoxy-a-phenylthio substituted ketones bearing an additional stereocenter in a1-position was prepared, and the reduction with chelating and non chelating reagents was studied. ''Internal matched'' pairs (leading to highly stereoselective processes) and ''mismatched'' pairs were identified, and possible transition structures were suggested.
