Yn. Bubnov et al., SYNTHESIS AND MOLECULAR-STRUCTURE OF TRANS-2-ALLYL-6-PHENYL-1,2,3,6-TETRAHYDROPYRIDINE HYDROCHLORIDE, Russian chemical bulletin, 45(11), 1996, pp. 2595-2597
When treated with triallylborane and MeOH, the product of the 1,2-addi
tion of PhLi to pyridine transforms to trans-2-allyl-6-phenyl-1,2,3,6-
tetrahydropyridine. The structure of its hydrochloride was established
by X-ray structural analysis.
