名称:
A synthesis of methyl 4,6-dideoxy-3-C-methyl-4-(N-methylacetamido)-α-d-altropyranoside, the 3-epimer of (methyl N-acetylsibirosaminide)
摘要:
The oxirane ring of 1,6:3,4-dianhydro-beta-D-talopyranose reacted at C-4 with methylamine, and the product, further processed gave a 3-deoxy-C-3-methylene derivative. Iodonium ion-induced cyclisation led to an iodooxazolidinone, and deiodination, followed by hydrolysis and N-acetylation, to the title compound.
