The Michael Addition-Elimination of Ylides to alpha,beta-Unsaturated (mines.Highly Stereoselective Synthesis of Vinylcyclopropanecarbaldehydes and Vinylcyclopropylaziridines

摘要

Much attention has been paid to the construction of multisub-stituted cyclopropanes,the basic structural elements in a wide range of biologically active compounds as well as important intermediates in organic synthesis.The tandem Michael addition-elimination of ylides to electron-deficient alkenes provides easy access to functionalized cyclopropanes.
