摘要:
The super silyl group governs high diastereoselectivity and yields for a sequential aldol-polyhalomethyllithium addition reaction. This unique silyl group is necessary to obtain the diastereoselectivities associated with this-sequential reaction, capable of generating two new stereocenters. alpha-Polyhalomethylcarbinols are generated with the simple and inexpensive dihalomethanes and trihalomethanes.
