Cycloadditions. 53. Stereoselective Synthesis of Functionalized Pyrrolidines via Intramolecular 1,3-Dipolar Silyl Nitronate Cycloaddition
摘要:
Michael addition products of secondary allylamines to nitroalkenes were captured as the O-silyl alpha-allylaminoalkylnitronates. These undergo stereoselective intramolecular silyl nitronate-olefin 1,3-dipolar cycloaddition to provide highly functionalized pyrrolidines.
