Abstract: Synthesis of 3-acyl-5,6-dihydro-1,4-oxathiines has been achieved via reactions of thiiranes and α-diazo-β-1,3-dicarbonyl compounds under microwave and copper sulfate-assisted conditions. The current method provides a direct and simple strategy in efficient preparation of 3-acyl-1,4-oxathiines from readily… read more here.

DOI: 10.1021/acs.orglett.2c03661
Abstract: Oligosaccharides are involved in numerous biological processes. Achieving optimal anomeric selectivity and regioselectivity remains challenging. Herein, we present a method for the oxidative glycosylation of thioglycosides with hypervalent iodine reagents derived from carboxylic acid to… read more here.
