  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.

  This application relates to para-quinol derivatives, such as analogues of manumycins, aranorosins and gymnastatins. This application also relates to methods of synthesizing and using the para-quinol derivatives. In one embodiment of the invention a compound having the chemical structure (I) is provided wherein X 1 and X 2 are carbon atoms either joined by double bond or joined by a single bond and comprising constituents of an epoxide ring or a hydroxyethylene moiety; X 3 and X 4 are carbon atoms either joined by double bond or joined by a single bond and comprising constituents of an epoxide ring; R 1 is selected from the group consisting of branched alkyl chains, unbranched alkyl chains, cycloalkyl groups, aromatic groups, alcohols, ethers, amines, and substituted or unsubstituted ureas, esters, aldehydes and carboxylic acids; and R 2 is selected from the group consisting of H, OH and NHR 3 wherein R 3 is a nitrogen protecting group. In a particular embodiment of the invention R 1 is a polyunsaturated carbon chain as found in biologically active manumycins. The applicant's synthetic method may involve diasteroselective formation of a spirolactone in an oxidative spiroannulation process using tyrosine or a tyrosine derivative having a chiral centre as a starting material.

  日期：1998.7

  An asymmetric approach to the mC(7)N epoxyquinone central unit of the manumycin antibiotics is described based on the enantioselective (89% ee) chiral phase transfer epoxidation of a substituted cyclohexenone. The chiral epoxide is employed in the first syntheses of the tide compounds in enantiomerically pure form. (C) 1998 Elsevier Science Ltd. All rights reserved.
