2-Azetidinones, fused polycyclic

Alcaide and coworkers have reported in 2002 the synthesis of various types of racemic and homochiral 1,3,4-trisubstituted- or fused polycyclic (3-lactams (III and IV, respectively, Fig. 9) via intermolecular 1,3-dipolar cycloaddition reaction of 2-azetidinone-tethered nitrones with a variety of alkenes or alkynes [264]. [Pg.164]

This section is devoted to tricyclic and polycyclic fused azetines, azetidines, and azetidinones. Since the publication of CHEC-II(1996), there has been a marked increase in activity in this area and a wide variety of different types of compounds have been studied. Other examples of these compounds are mentioned in CHEC(1984) and CHEC-11(1996), and should be consulted in addition to this section. [Pg.287]
