  Use of Aziridines for the Stereocontrolled Synthesis of (−)-LL-C10037α, (+)-MT35214, and (+)-4-epi-MT35214

  摘要：

  Strategies for the synthesis of the title compounds have been developed using a diastereoselective aziridination reaction of 4-O-substituted cyclohexenones. Aziridination using a chiral amine permitted resolution of a 4-hydroxycyclohexane derivative, and this resulted in the synthesis of both enantiomers of the title compound. Alternatively, the chiral 4-hydroxycyclohexenone starting material was derived from quinic acid. In both cases stereoselective epoxidation and opening of the aziridine ring with hydrazoic acid afforded the 2-azidocyclohexenone, which was transformed to the 2-acetamido group present in the natural product.

  [reaction: see text] The directing ability of an aziridine group for the epoxidation of adjacent double bonds is demonstrated. The aziridine group is also used to effectively protect a double bond in a cycloenone system for a short synthesis of the title compound.
