Cycloadditions step-economical synthesis

Compared with the single-bond construction approach of (3-lactam synthesis, the ketene-imine cycloaddition, which includes carbenoid insertion and the Staudinger reaction, have been widely used [56, 65]. Due to the ready availability of both imines and ketenes, the Staudinger reaction has provided a useful and economical approach for the synthesis of (3-lactams. In addition, the ketene-imine cycloaddition is efficient, which constructs the (3-lactam four-member ring in just one-step... [Pg.265]
