Synthesis and transformations of tetrazolylacroleins
摘要:
1-Methoxy-4-aryltetrazolyldienes have been subjected to oxidative degradation to yield tetrazolyl acroleins. These compounds when reacted with 1,1-dimethylhydrazine gave 1-dimethylamino-4-aryltetrazolyl-1-azadienes. Both the acroleins and the new 1-azadienes underwent ring transformation in reaction with fumaronitrile to afford pyrazolyl derivatives. (C) 2003 Elsevier Ltd. All rights reserved.

either azolyltrienes in a Wittig reaction, or to undergo cyclization to a dihydrobenzene containing the azole substituent. Transformation with an aza-Wittig reagent gave tetrazolylpyridines. The ambidentreactivity was found to be dependent on the substituent of the phosphorane, which was rationalized by ab initio (DFT) calculation of the atomic charges of the reaction centres.
