Significance
A highly diastereoselective and general method for the addition of variously substituted alkenylzinc reagents to α-silyloxy ketones is reported. An excess of alkylzinc halide as Lewis acid leads to the formation of chelation-controlled products in diastereomeric ratios greater than 18:1.
