Article abstract of DOI:10.1246/cl.1981.1737

Flash vacuum pyrolysis of 2-benzylpyridine N-oxides afforded pyrido<1,2-a>indole and its various methyl-substituted derivatives in moderate yields.Benzoquinoline in the pyrolyses of 2-(o-methylbenzyl)pyridine N-oxide and 2-benzyl-3-methylpyridine N-oxide, and 2-(β-styryl)pyridine in the reaction of 2-(β-phenethyl)pyridine N-oxide were major products as exceptional cases.
