A synthesis of bredinin (Mizoribine®) from an acyclic precursor
摘要:
Bredinin (4-carbamoyl-1-beta-D-ribofuranosylimidazolium-5-olate, 1) was synthesised by the formation of a malonamate from 2,3-isopropylidene-D-ribofuranosylamine and ethyl malonyl chloride, followed by a sequence involving amination, via reduction of an oxime, heterocycle formation and then deprotection.
