D,L-(3aS,6aR)-1,3-二苄基-4-氢-4H-呋喃[3,4-d]咪唑-2,4(1H)-二酮在BMImBF4离子液体中,于45℃酶催化水解反应8h得D-式异构体,收率45.0%,e.e.值90.4%。
A method was developed for direct enantio-selective hydrolysis of D, L-(3aS,6aR)-1,3- dibenzyl-tetrahydro- 4H-furano[ 3,4-d ] imidazole-2,4 (1H) -diketone ( Ⅰ ) to form the corresponding D-(3aS,6aR) -1,3-dibenzyl-tetrahydro-4H-furano [ 3,4-d ] imidazole-2,4 (1H) -diketone ( Ⅱ ) in the presence of a fungal esterase fromfusarium sp.. 45.0% yield with 90.4% e.e. was obtained for 8 h at 45℃ in an esterase (activity 500 U · g^-1)/BMImBF4 (1-butyl-3-methylimidazolium tetrafluoroborate) ionic liquids system.
