A five-step practical and stereocontrolled synthesis of α- and β-pseudouridines from d-ribonolactone is described. The key step involves a highly stereoselective reduction of a hemiketal C-nucleoside intermediate in each case. Multi-gram quantities of β-pseudouridine can now be made available.
描述了从d-核糖内酯的α-和β-伪杜鹃碱的五步实用和立体控制的合成。关键步骤涉及在每种情况下高度立体选择性地还原半立体C-核苷中间体。现在可以提供多克数量的β-伪尿苷。
