2-Substituted 1,2-dihydropyridines including an optically active one were regioselctively prepared from 2-substituted piperidines through three intermediates, that is, (a) 1,2,3,4-tetrahydropyridines, (b) 5-bromo-6-methoxypiperidines, and (c) 1,2,3,4-tetrahydro-6-methoxypyridines.

A new method using electrochemical oxidation has been exploited for the stereoselective synthesis of 2,3,6-trihydroxylated 5S-piperidine derivatives. The electrochemical method was successively used for the conversion of N-protected piperidines to N-prote

β,γ-Unsaturated N-alkoxycarbonyl-α-methoxypiperidines, which were prepared from N-alkoxypiperidines by using anodic oxidation in a key step, were regioselectively alkylated at the α-position by using Grignard reagents in the presence of BF3*Et2O, whereas in the presence of CuBr, the alkylation took place at the γ-position.
