    通过环状硫酸盐中间体高效合成手性α,β-环氧酯
    摘要:
    手性α,β环氧酯的有效的合成1从手性2,3- dihydroxyester 2已经研制成功。将酯2转化为相应的环状硫酸盐3,将其在室温下用THF中的LiBr或在丙酮中的Bu 4 NBr打开,以提供2-溴-3-羟基酯4。在甲醇中在低温下用K 2 CO 3处理4,得到的α,β-环氧酯1的总收率极好,且ee与起始二醇相同。

    摘要:
    Two beta-(alkyl)-beta-hydroxy-alpha-amino acids [alkyl = But, BnO-(CH2)(3)-] have been synthesized by a sequence based on Sharpless asymmetric dihydroxylation. The key sulfate intermediates were prepared from enantiomerically enriched diols by direct treatment with sulfuryl chloride. The scope and the appropriate conditions for sulfate formation have also been studied. (c) 2005 Published by Elsevier Ltd.

    An efficient synthesis of chiral α,β-epoxyester 1 from chiral 2,3-dihydroxyester 2 has been developed. Ester 2 is converted to the corresponding cyclic sulfate 3, which is opened with either LiBr in THF or Bu4NBr in acetone at rt to furnish 2-bromo-3-hydroxyester 4. Treatment of 4 with K2CO3 in methanol at low temperature gives α,β-epoxyester 1 in excellent overall yield and in the same ee as in the
