[00124] [3aS-[1(E),3a,6,7a]]-1-[3-(3,4-difluorophenyl)-1-oxo-2-propenyl]-hexahydro-8,8-dimethyl-3H-3a,6-methano-2,l-benzisothiazole-2,2-dioxide: At 0-5 0C, a solution of 3-(3,4-difluoro-phenyl)-acryloyl chloride in dichloromethane (30 mL) was added to a mixture of (2R)-bornane-10,2-sultam (14.5 g, 67.35 mmol, 1.00 equiv), triethylamine (20.4 g, 201.98 mmol, 3.00 equiv), and dichloromethane (120 mL). The resulting solution was stirred at ambient temperature for about 3 hours and then water (40 mL) was added. Standard extractive workup with dichloromethane (2 x 40 mL) gave the title product as an off-white solid (18.5 g; yield = 72 percent). 1H NMR (300 MHz, CDCl3) delta: 7.68 (d, / = 15.6 Hz, 1 H), 7.15- 7.45 (m, 3 H), 7.19 (d, J = 15.6 Hz, 1 H), 4.00 (m, 1 H), 3.55 (q, J1 =13.8 Hz, J2 = 24.0 Hz ), 2.18 (m, 2 H), 1.93 (m, 2 H), 1.37-1.48 (m, 2 H), 1.22 (s, 3 H), 0.96 (s, 3 H).
With the complex challenges of chemical substances, we look forward to future research findings about (3aS,6S,7aS)-8,8-Dimethylhexahydro-1H-3a,6-methanobenzo[c]isothiazole 2,2-dioxide
