摘要:
Stereoselective synthesis of 3'-C-methylene- and 2'-methyl-3'-C-methylene-3'-deoxythymidine is described, the key reaction being the formation of 3-C-methylene function by catalytic isomerization of a chiral epoxyalcohol, prepared from commercially available 3-methyl-2-butenal and 3-methyl-2-pentenal.
