Synthesis of d -mannofuranosyl-ethanethioamides and the corresponding ethanedithioate, the first C -glycosyl derivative with thioacylating properties
摘要:
D-Mannofuranosyl-ethanethioamides were prepared in gold yields via a Homer-Wadsworth-Emmons reaction of thiocarbamoylmethylphosphonates with 2,3:5,6-di-O-isopropylidene-alpha-D-mannofuranose. New glycosyl-ethanethioamides were obtained and one of them was converted into the corresponding dithioester which is a potential sugar substituted thioacylating agent for aminoacids.

The Horner-Wadsworth-Emmons reaction of the first, third and fourth generation of aldehyde terminated dendrimers 1-[Gn] (n=1: 6 CHO, n=3:24 CHO, n=4:48 CHO groups, respectively) with phosphonates unsubstituted at the carbon α to the phosphoryl group 2a-i affords in moderate yield dendrimers bearing various α,β-unsaturated functional groups on the surface, including amino acid derivatives.
