|Title:||A new entry to the synthesis of substituted azetidines: [2+2] cycloaddition reaction of four-membered endocyclic enamides to ketenes|
|Abstract:||The first example of a [2+2] cycloaddition reaction of a four-membered endocyclic enamide (2-azetine) to dichloroketene is described and constitutes a new entry to the synthesis of substituted azetidines. Preliminary studies concerning the Baeyer Villiger oxidation of the [2+2] cycloadduct revealed an unusual regioselectivity. The synthesis of a new azetidine-3-carboxylic acid derivative from the [2+2] cycloadduct is also presented. (c) 2006 Elsevier Ltd. All rights reserved.|
