us to obtain 2-pyrrolidones with oxo and cyano groups in the substituent at the nitrogen atom, because the reduction amination process was accompanied by hydrogenation of these functional groups. Introduction of an oxoalkyl substituent at the nitrogen atom of pyrrolidin-2-ones offers the possibility to modify their structures by reactions involving the oxo group, which leads to the synthesis of new
A procedure for one-pot intermolecular radical addition of 2-iodoesters to terminal alkenes followed by azidation of the radical adduct has been developed. This sequential reaction represents an alkene carboazidation process. Its efficacy is demonstrated by the two-step preparation of various lactams such as pyrrolidinones, pyrrolizidinones, and indolizidinones. An easy access to spirolactams bearing an amino-substituted quaternary carbon center is also described. These compounds are important building blocks for the synthesis of numerous alkaloids such as, for instance, FR901483.
