摘要

The nmr spectrum of heptaniethyl-3-pyrroline (XIIIa) showed three singlets at T 9.09, 8.65, and 7.91, respectively, with peak height ratios of 4: 2: 1. The infrared spectrum showed a peak at 6.03 p but no peaks in the 10-11-p region indicating a tetrasubstituted double bond. The nmr spectrum of 3-methylene-2, 2, 4, 5, 5-pentamethylpyrrolidine hydrochloride (XIV
