摘要
Lithium base promoted stereoselective Michael addition of thiols to N-methacryloylcamphorsultam produced the corresponding addition products in 66% to 90% diastereoselectivity. Hydrolysis of the Michael product with three equivalents of lithium hydroxide in THF/H2O gave the corresponding optically active beta-thioester with no sign of any racemization, and recovered camphorsultam quantitatively.
