Highly Efficient 1,4-Addition of 1,3-Diesters to Conjugated Enones by In/TMSCl
摘要:
Organoindium reagents derived from indium and diethyl bromomalonates were added to a wide range of conjugated enones in a 1,4-fashion in the presence of TMSCl under mild conditions, and corresponding oxo-1,3-diesters were obtained in good to excellent yields.
