摘要
Catalytic highly enantioselective (up to > 99% ee) and diastereoselective (up to 99% de) direct Michael addition of ketones and aldehydes to beta-nitrostyrenes have been achieved with readily accessible and highly tunable prolinal dithioacetal catalysts. (c) 2007 Elsevier Ltd. All rights reserved.
