D- and L-arabinose respectively have been achieved by two different routes. The conversion of (1) to 6S-(3R-acetanilido)-3,6-dihydro-2H-pyranyl-N,N-dimethylacetamide (3), a key intermediate in the synthesis of pseudomonic acids, is described.
通过两种不同的方法分别从D-和L-阿拉伯糖合成1S,6S-3,7-二氧杂双环[4.3.0] non-4-en-8-one(1)和对映异构体(2)的对映体特异性合成路线。描述了将(1)转化为6S-(3R-乙酰胺基)-3,6-二氢-2H-吡喃基-N,N-二甲基乙酰胺(3)的合成过程,是伪酸合成的关键中间体。
