✦ Synopsis
The reaction of to-oxo-(x,13-unsaturated esters with lithium thiolates afforded the Michael-aldol tandem cyclization products in good to perfect stereoselectivity depending on the nature of thiolates.
📜 SIMILAR VOLUMES
The asymmetric reaction of v-oxo-a,b-unsaturated esters with lithium chiral thiolates afforded the Michael-aldol tandem cyclization products in high yield and good stereoselectivity. Reductive desulfurization gave the corresponding optically pure 2-hydroxycycloalkanecarboxylates.
