Abstract
The reaction of methyl 2-(3-chloro-1,4-dioxo-1,4-dihydronaphthalen-2-yl)propenoate (2a) with primary amines gave 4-chloro-5-hydroxy-3-methoxycarbonyl-1H-benzo[g]indoles 5a-f as major compounds and 3-methoxycarbonyl-4,9-dioxo-2,3,4,9-tetrahydro-1H-benzo[f]indoles 6a-d as minor ones. Whereas the reaction of 3-(3-chloro-1,4-dioxo-1,4-dihydronaphthalen-2-yl)-3-buten-2-one (2b) with primary amines afforded the corresponding 1H-benzo[g]indoles 5g-i as major products and 3-acetyl-4,9-dihydro-4,9-dioxo-1H-benzo[f]indoles 7g, h as minor products.
