摘要
Ester-substituted allenic aldehydes 1, 4, 6a, and 6b undergo reductive cyclizations when treated with SmI2. These conversions are completely regioselective and in the case of 4 occur with high diastereoselectivity. Product formation is crucially dependent on the choice ef solvent and proton source.
