The scalable and economical total synthesis of two building blocks [Fmoc‐GlcAPU(Me)‐OH and Fmoc‐GalAPU(Me)‐OH] is described. The syntheses proceed in nine consecutive steps, starting from methyl α‐d‐glucopyranoside, and use the nonselective reduction of a new oxime intermediate as a key step.
描述了两个构件[Fmoc-GlcAPU(Me)-OH和Fmoc-GalAPU(Me)-OH]的可扩展且经济的总合成。合成过程从甲基α- d-吡喃葡萄糖苷开始,共分九步进行,并将新的肟中间体的非选择性还原作为关键步骤。
