Radical reaction of (N-methyl-7-bromo-2,2-dimethyl-2-silatetralin-6-ylamino)veratramide (8a) and -piperonamides (8b) in boiling benzene using tributyltinhydride and AIBN gave two kinds of N-methylphenanthridinone derivatives (15 and 16), which were cyclized at 6-and 2-positions of aroylic acid moiety. On the other hand, similar reaction of N-methyl-N-(2-bromoveratryl and 2-bromopiperonyl)-2,2-dim
