  DDQ-Mediated Oxidative Coupling: An Approach to 2,3-Dicyanofuran (Thiophene)

  摘要：

  A facile oxidative coupling of alpha-carbonyl radicals to 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) for the synthesis of 2,3-dicyanofurans and thiophenes starting from readily available beta-diketones, simple ketones, and beta-keto thioamides in up to 95% yield in one step was developed. Mechanistic investigations revealed that a radical process could be involved in this transformation, and a water promoted C-C bond cleavage pathway is proposed for the formation of 2,3-dicyanofurans and thiophenes.

  日期：2000.2

  N-Alkyl-N-arylthiocarbamoylacetates, the key intermediates for the synthesis of novel antinephritic agents, have been prepared for the first time. Some of the esters were in turn hydrolyzed to the corresponding acids, An alternative, indirect synthetic route was also developed to prepare some unusual acids.
