beta-ketophosphonate skeleton in these heterocycles allowed their use as substrate in the cyclic Horner-Wadsworth-Emmons reaction with aldehydes or ketones furnishing chiral alpha,beta-unsaturated ketones - a new class of building block in organic synthesis.

4-羟基-2-氧-4-烷基/-芳基-烷基-膦酸酯的两种对映异构体通过化学酶促制备,并使用分子内OH插入反应催化转化为手性2-磷酰基-3-氧-5-烷基/-芳基四氢呋喃。醋酸铑(II)。所得四氢呋喃的潜在生物活性非常令人感兴趣。这些杂环中 β-酮膦酸酯骨架的存在允许它们在与醛或酮的循环 Horner-Wadsworth-Emmons 反应中用作底物,提供手性 α,β-不饱和酮 - 有机合成中的一类新结构单元。((C) Wiley VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)。
