A nonstabilized azomethine ylide reacts with a wide range of substituted isatoic anhydrides to afford novel 1, 3-benzodiazepin-5-one derivatives, which are generally isolated in high yield. The transformations involve 1, 3-dipolar cycloaddition reactions of the ylide with the anhydrides to give transient, and in a representative case spectroscopically observable, oxazolidine intermediates that undergo ring-opening− decarboxylation− ring-closing ...
