  Erythrulose derivatives as functionalized chiral d3 and d4 synthons

  摘要：

  Protected erythrulose derivatives have been shown to undergo highly stereoselective dicyclohexylboron chloride-mediated aldol reactions. After suitable synthetic manipulation of the resulting aldol adducts, chiral polyoxygenated molecules can be obtained in which either three or all four carbon atoms of the starting erythrulose molecule have been incorporated. Erythrulose derivatives may therefore behave, according to convenience, as chiral, functionalized d(3) or d(4) synthons. As an example, this methodology has been applied to a stereoselective synthesis of the naturally occurring, pharmacologically active lactone (+)-boronolide. (C) 2002 Elsevier Science Ltd.
