Aza-Michael reaction promoted by aqueous sodium carbonate solution
摘要:
A general and efficient aza-Michael reaction promoted by aqueous sodium carbonate solution has been developed. The reaction has complete mono-alkylation selectivity and proceeds with complete chirality retention for chiral amino esters. With a broad substrate scope, a well-common catalyst and simple operation, the catalytic approach provides a facile, practicable, economical, and environmentally benign method for the synthesis of beta-amino carbonyl compounds.

[chemical reaction: see text]. 4-Hydroxypiperidin-2-ones may be prepared in highly diastereoselective fashion using a Cu(I)-catalyzed reductive aldol cyclization of alpha,beta-unsaturated amides with ketones. Used in combination with proline-catalyzed asymmetric Mannichreactions, this methodology enables the enantioselectivesynthesis of more highly functionalized piperidin-2-ones and hydroxylated
