condensed dihydropyridones 6 could be synthesized from a-amino esters 2 or 3 and o-bromobenzyl bromides or heterocyclic analogues 1. These products resemble isoquinoline and β-carboline alkaloid structures and could be stereoselectively transformed into condensed 4-hydroxytetrahydropyridines 7 and 8 by reaction with Grignard reagents or reduction. Treatment of condensed 4-allyl or 4-homoallyl-4-hydroxypyridines
