| Abstract: | Hydroboration of N-substituted 5 - methyl - 4 - phenyl - 1,2,5,6 - tetrahydropyridines gave, as a sole product, the 5-methyl-4-phenyl-3-piperidinols, while the 3 - methyl - 4 - phenyl - 1,2,5,6 - tetrahydropyridines gave the 3-methyl-4-phenyl-3-piperidinols together with the 4-boryl-3-methyl-4-phenylpiperidine amine boranes. Structural and configurational assignments were made through the analysis of spectral data (IR, 1H NMR and MS). |
