with 1-chloro-1-(dimethylamino)-2-methyl-1-propene in dichloromethane at 20; for 2 h;Inert atmosphere;
Steps:
4.6.7. Reaction of 4-hydroxy-4-methylpentan-2-one with 2a.
Procedure B: 0.37 g (3.2 mmol) hydroxyketone, 0.47 (3.5 mmol) 2a, 2 h. A 2/1 mixture of chloride and alkene was obtained as shown by 1H NMR. For chloride: 1H NMR (200 MHz, CDCl3): 2.95 (s, 2H,CH2COCH3), 2.2 (s, 3H, COCH3), 1.70 (s, 6H, (CH3)2CCl). For vinylketone: 1H NMR (200 MHz, CDCl3): 6.10 (m, 1H, HC=C), 2.20 (s, 3H, COCH3), 2.14 (d, J=1.2 Hz, 3H, CH3C=), 1.89 (d, J=1.2 Hz, 3H, CH3C=).
