摘要

The products, 5a, 5b, and 5c were identified by their spectral data. All new compounds gave satisfactory analytical and spectral data. Data for selected compounds are given below. 3a: bp. 135–137°C/2 mmHg. IR (neat) 3400, 2200, 1640, 1270, 1175, 960, 700 cm −1 . 1 H NMR (CDCl 3 ) δ1.64 (s, 6H), 2.90 (s, 1H), 7.20–7.60 (m, 3H), 8.00–8.15 (m, 2H). 4a: mp. 102.9–103.8°C. IR (KBr) 1855, 1830, 1675, 1620, 1270, 1150, 995 cm −1 . 1 H NMR ...
