  Synthesis, X-ray crystallography and computational studies concerning an oxadiazinone derived from d-camphor: a structural limitation of oxadiazinones as chiral auxiliaries

  摘要：

  A camphor-based oxadiazinone was prepared by reaction of the N-nitroimine of D-camphor with (1R,2S)-norephedrine; the reduction of the resultant imine; N-nitrosation of the amine; reduction to the corresponding hydrazine and cyclization. The conformational behaviour of oxadiazinone 7 was modeled in the gas and solution phases using the semiempirical AM1 method and density functional theory. Application of the oxadiazinone in the titanium mediated asymmetric aldol reaction provided the highly diastereoselective formation of the expected syn-adducts 8a-d as evidenced by single crystal X-ray diffraction analysis. Attempts to remove the oxadiazinone auxiliary using acidic or basic conditions failed to yield the expected beta-hydroxyacid in significant yield. (C) 2005 Elsevier Ltd. All rights reserved.
