9-Methylenelongibornane: Lewis Acid-induced Transannular Hydride Shift/Rearrangement to 9-Methylisolongifolene/7-Isopropyl-1,1,3-trimethyltetralin

9-Methyllongibornyl-9-cation (5, R=Me) generated from 9-methylenelongibornane (2), on exposure to BF3*OEt2 in benzene, has been shown to undergo a transannular 1,5-hydride shift in the "reverse" fashion (C-2 to C-9) to give the crucial 9-methyllongibornyl
