A convenient synthesis of tetrazolo[1,5-a]-α-cycloalkanones
摘要:
A convenient synthesis of a series of tetrazolo[1,5-alpha]-alpha-cycloalkanones 4a-d with the carbonyl group attached at the tetrazole carbon is described. The sequence entails the formation of an exocyclic olefin at the alpha-methylene position and subsequent ozonolysis. The reactions proceed under mild conditions, and the tetrazole moiety is well tolerated. (c) 2006 Elsevier Ltd. All rights reserved.
