N 6-Bis-demethylated xylo-puromycin analogue 2 was synthesized over six steps in 56% yield from adenosine 3, involving a Mattocks bromoacetylation, a regio- and stereoselective ribo-epoxide ring opening with sodium azide and an efficient Staudinger-Vilarrasa reaction to couple the amino acid to an azide precursor.
N 6-双甲基木糖-嘌呤霉素类似物2由腺苷3通过六个步骤合成,产率为56%,其中涉及Mattocks溴乙酰化、区域和立体选择性核糖环氧化合物与叠氮化钠的环氧化合物开环以及将氨基酸与叠氮化物前体偶联的高效Staudinger-Vilarrasa反应。
