Example 3Step 1. Synthesis of (3aS,6R,7aR)-1 -methacιyloyl-8,8-dimethylhexahydro-3a,6-methano-2,1- benzisothiazole 2,2-dioxide.(1 S)-(-)-2,10-camphorsultamProcedure: To a solution of the (1S)-(-)-2,10-camphorsultam (5.00Og, 23.22 mmoles) in anhydrous THF (50ml) at -20° C was added lithium chloride (1.08g, 25.5 mmoles, - small balls), triethylamine (4.21 ml, 30.2 mmoles, 1.30 equivalents.) and then the mixture was allowed to stir for 10 minutes. The lithium chloride did not go into solution. 2-methylacrylic anhydride (4.15 ml, 27.9 mmoles, 1.20 equivalents.) in THF (15ml) was then added. The internal temperature varied between -20° C and -10° C during addition which took about 5 minutes. The thick white mixture was stirred within the cooling bath and allowed to reach room temperature. After stirring overnight the white heterogeneous reaction mixture was added to 350ml of water with stirring. The white crystalline solid (3aS,6R,7aR)-1 -methacryloyl-8,8- dimethylhexahydro-3a,6-methano-2,1-benzisothiazole 2,2-dioxide (6.302g, 96percent yield) was collected and dried under vacuum.-Analytical HPLC run with a Vydac 218TP54 C18 reverse phase column run with solvents A: 0.1percent trifluoroacetic acid in H2O and B: 0.1percent trifluoroacetic acid in acetonitrile. Gradient (0 to 100percentB) over 22 minutes. Retention time 18.166 min (100percent).Optical rotation = 0.02Og in 2ml; c=0.01g/ml (C= 1 (CHCI3)}; measurement -0.226; optical rotation = - 0.226x4000/10 = - 90.4.Combustion Anal sis:Steps 2 through 5 were performed as in Example 2. |
