CYCLOADDITIONS TO KETENE-S,N-ACETALS. NEW SYNTHESES OF BENZO- AND NAPHTOFURANS, 1-BENZ- AND NAPHTHOZEPINS, AND BENZFURAN-2-ONES

Annulation of ketene-S,N-acetal with 1,4-quinones gave benzo- and naphtofurans which were converted to 1-benz- and naphthoxepins and benzofuran-2-ones.

Ketene S,N-Acetals as Synthetic Intermediates for Heterocycles. Reaction of Ketene S,N-Acetals with 1,4-Quinones

Annelation of ketene S,N-acetals with 1,4-quinones is found to give benzo- and naphthofurans bearing enamine groups.Subsequent enamine reaction allows the formation of 1-benz- and naphthooxepines and benzofuran-2-ones.
