  Stereoselective construction of quaternary centers at ambient temperature by the highly stereocontrolled migration of groups containing sp-, sp2-, and sp3-hybridized carbon atoms

  摘要：

  A very highly diastereoselective semipinacol rearrangement of 2,3-epoxy alcohols mediated by tin(IV) chloride at ambient temperatures is shown to be applicable to a wide variety of migrating groups including methyl, tert-butyl, cyclopropyl, vinyl, alkynyl, phenyl, and 2-furyl. A synthetically valuable feature is that a mixture of syn- and anti-epoxy alcohols affords only a single diastereoisomerically pure beta-hydroxy ketone. Additional advantages of the reaction include the presence in the product of two adjacent stereocenters and the efficient creation of a new quaternary center, valuable features in the synthesis of a variety of natural products.

The competitive radical reaction to produce CPB and a small amount of by-products generated from the thermally-induced synthesis by the non-selective radical reaction was restricted solely to the
