An easy and straightforward synthesis of 6,10b-diarylhexahydrobenzo[f]isoquinoline by the repeated treatment of boron trifluoride etherate (BF(3) x OEt(2)) is reported. The overall transformation from 4-arylpiperidin-3-one to benzo[f]isoquinoline proceeds via ring contraction, chain elongation, and intramolecular electrophilic cyclization in moderate yields.

Methyl santalbate (methyl trans-11-octadecen-9-ynoate) from Sandal wood seed oil, Santalbum alum) was epoxidized to methyl trans-11,12-epoxy-octadec-9-ynoate (1). Treatment of compound 1 with tetrabutylammonium dihydrogentrifluoride, and boron trifluoride etherate gave the corresponding anti- (2a) (57%) and syn- (2b) (35%) fluorohydrin derivatives
