Naphtho quinolin-7-ones

Cyclization of 6-(arylcarbonyl)methyl-2-aryl-77/-naphtho[l,2,3-with hydrazine hydrate gave 1,2-diazepine derivatives 61 <2003AJC1219> (Equation 6). 

Further details have appeared of the one jx)t synthesis of naphtho[2,l-g]quinoline-7,12-dione derivatives (250) from irradiation of the quinolinedione (251a) in the presence of l,l-diarylethylenes. The same workers have more fully described their earlier findings on the formation of (252) and thence (253) from the photoinduced reaction of dichloronaphtho-1,4-quinone (251b) and the ethylenes. In this latter system, CIDNP studies have... 

Quatemization of the i ridylnaphthalene derivatives (132) followed by reduction affords a mixture of diastereoisomers of which only one undergoes acid catalysed cyclisation to the partially reduced cis-fused naphtho[1.8-f.g]quinoline (E. Reimann and G. Bauer, Arch.Fharm.. 1984, 317, 517). The C-nmr shifts for the angular methyl group lie between 6 28 and 35 in the six...
