  Demonstration of 14–20-membered intramolecular carbonyl ylides: diastereoselective synthesis of macrocycles incorporating spiro-indolooxiranes

  摘要：

  A range of macrocycles (13-19-membered) possessing spiro-indolooxirane unit were synthesized with complete diastereoselectivity in good yield by the rhodium(II) acetate catalyzed reaction of substituted cyclic diazoamides in dry dichloromethane. The reaction proceeds via the formation of the corresponding macrocyclic carbonyl ylide followed by a con-rotatory electrocyclization process. (C) 2011 Elsevier Ltd. All rights reserved.

  Generation of intramolecular macrocyclic carbonyl ylides from aldehyde group tethered to diazoamides in the presence of rhodium(II) acetate and their successful [3+2]-cycloaddition afforded the corresponding macrocycles incorporating spiro-indolofurans, -indolofuropyrroles, -indolofurofurans, and -indolodioxolanes in moderate to good yield with complete diastereoselectivity. The competition between the electrocyclization and [3+2]-cycloaddition reactions of macrocyclic carbonyl ylides was also demonstrated. (C) 2011 Elsevier Ltd. All rights reserved.
