F. Fernandez et al., A convenient route to both enantiomers of endo-2-benzonorbornenol via lipase catalysed resolution of the racemic mixture, TETRAHEDR-A, 12(3), 2001, pp. 365-368
Resolution of racemic endo-benzonorbornenol (+/-)-4 was performed using Can
dida antaretica lipase (Novozym" 435) in benzene (50 degreesC;50 hours) wit
h vinyl acetate as the acyl donor to afford (-)-endo-2-benzonorbornenol (-)
-6 and their corresponding (+)-endo-2-benzonorbornenyl acetate (+)-5 in hig
h e.e.s of up to 99'% and workable yields of up to 45-46%. (C) 2001 Elsevie
