An unexpected reversal of stereochemistry in a modification of the rychnovsky cyanohydrin alkylation

Alkylation of cyanohydrin 1,3-acetonides with unsaturated substitution at the 2-position is described. The stereochemistry of the products obtained from this reaction was opposite to that anticipated. Alkylation of cyanohydrin 1,3-acetonides with unsaturated substitution at the 2-position is describ...
