  Ketene-S,S-acetals as 1,3-dipolarophiles towards azides. A new synthetic entry into cyclic amino acids

  摘要：

  Intramolecular azide cycloaddition reactions of ketene-S,S-acetals proceed to give a reactive imine as the initially-formed intermediate and this mechanism is supported by thermolysis of (18) which gave the stable imine (22). N-Acylation of this intermediate leads to cyclic variants of 2-amino ketene-S,S-acetals (20, 24, 27), which can be viewed as masked alpha-amino acids, and reduction leads to the corresponding dithiane (21, 25, 29a). Both systems have been converted to cyclic alpha-amino acids and the scope, in terms of the ring sizes available, and the limitations of this intramolecular cycloaddition process are discussed.
