Abstract

An unexpected ring enlargement, accompanied by oxidative–reductive transformation of the nitromethylene group, was brought about in almost quantitative yield by the reaction of (Z[hair space])-3-benzyl-2-(nitromethylene)thiazolidine (1a) and sodium hydroxide. The suggested mechanism is based on MS measurements involving isotope-labelled compounds.
