YieldReaction ConditionsOperation in experiment
With thionyl chloride
With oxalyl dichloride; N,N-dimethyl-formamide In dichloromethane for 3.5h; Ambient temperature;
With oxalyl dichloride In toluene at 50℃; for 3h;
With thionyl chloride for 5h; Heating;
With thionyl chloride In 1,2-dichloro-ethane for 5h; Heating;
With thionyl chloride for 24h; Heating;
With thionyl chloride for 5h; Heating / reflux; 14 The mixture of 3g menthyoxylacetic acid in 10g SOCl2 was refluxed for 5hrs and then SOCl2 was removed. Five milliliters of toluene was added and evaporated at reduced pressure to drive the residual SOCl2, 3.5g brownish residue was dissolved in 50ml CH2Cl2 and to which 2g racemic clausenamidone(+/-5) was added. Pyridine lml was added while cooling, and stirred 4hrs at room temperature. Two spots were showed by TLC. The reaction mixture was washed successively with 2N HCl, saturated NaHCO3 aqueous solution, saturated NaCl aqueous solution and dried over Na2SO4. After removing the solvent 5.4g of bromnish solid was obtained. After first recrystallization from methanol to give -7*, the mother liquid was chromatographed on silica gel column eluted with ethyl ether/hexane (2:1) to give +7* and more -7*.(-7*): 1.06g,yield 30.9%(theoretical yield 50%),m.p.:177-178 DEG C, [ alpha ] <1>D<8> =-249 DEG (c 0.21,CHCl3).(+7*): 0.86g, yield 24.8%(theoretical yield 56%),m.p.:152-153 DEG C, [ alpha ]<2>D<0> =+156 DEG (c 11,CHCl3).(-7*) and (+7*) were hydrolyzed separately in 30ml methanol catalyzed by PTS. After refluxing for 2hrs. Methanol was taken off by evaporation and the residue was dissolved in CH2Cl2.The CH2Cl2 solution was first washed with acid and followed by base and water.(-)clausenamidone(-5*) and (+) clausenamidone(+5*) was obtained respectively from (-7*) and (+7*) after removal of solvent.(-)clausenamidone(+5) yield 88%, m.p.:193-194 DEG C , [ alpha ]<1>D<8> =-340 DEG (c=0.22,CH3OH).(+)clausenamidone(-5) yield 82%, m.p.:193-194 DEG C , [ alpha ] <1>D<8> =+339 DEG (c=0.21,CH3OH).(-)clausenamidone(-5*) 0.59g was reduced as described in Example 8 with 0.11g NaBH4.Recrystallization from methanol of the product gave 0.5g of levoclausenamide, yield 83%, m.p.:162-163 DEG C , [ alpha ] <1>D<8> =-145 DEG (c=0.24,CH3OH).
