alkylation of an α-cyano-carbanion derived from 1,2-O-isopropylidene-3-deoxy-β-L-threo-pentofuranuronitrile 6 as chiral template has been developed; the method has been applied to the stereocontrolled synthesis of optically active 4-demethoxy feudomycinone C 4.
通过从1,2-衍生的α氰基碳负离子的烷基化潜在叔醇的对映和非对映控制构造的有效方法ö异亚丙基-3-脱氧-β-大号-苏pentofuranuronitrile 6手性模板已经被开发出来; 该方法已应用于光学活性的4-脱甲氧基Feudomycinone C 4的立体控制合成。
