Intramolecular Alkylations of Aromatic Compounds, IX: Synthesis of N-Methyl-8-(3-methoxybenzyl)-1,2,3,5,6,7,8,8a-octahydroquinoline and N-Methyl-9-(3-methoxybenzyl)-1,2,3,6,7,8,9,9a-octahydro-5H-cycloheptenopyridine

Dammertz, Wolf,Reimann, Eberhard

, p. 826 - 832 (1980)

The benzylidene compounds 8a and 8b, obtained by condensation of the 2,3-cycloalkenopyridines 7a and 7b with 3-methoxybenzaldehyde, are converted by catalytic hydrogenation to their benzyl derivatives 9a and 9b.Reduction of the corresponding methoiodides 10a and 10b with sodium borohydride leads to the title compounds 11a and 11b.
