Reactions of (4 E )-3-Arylamino-4-(hydroxyimino)naphthalen-1(4 H )-ones and (4 E )-2-[Arylamino(alkylamino)]-4-(hydroxyimino)naphthalen-1(4 H )-ones with 2,2-Dihydroxyindane-1,3-dione

The reactions of 3-arylamino-1,4-naphthoquinone-4-oximes with 2,2-dihydroxyindane-1,3-dione proceed without involving the oxime group and lead to (6E)-5-arylamino-4b,11b-dihydroxy-6-hydroxyimino-4b,5-dihydrobenzo[f]indeno[1,2-b]indole-11,12(6H,11bH)-diones. The reactions of 2-arylamino(alkylamino)-1,4-naphthoquinone-4-oximes with 2,2-dihydroxy-1,3-indandione involve the oxime group and lead to 6-[arylamino(alkylamino)]-6b,11b-dihydroxy-5,7-dioxo-5,6b,7,11b-tetrahydrobenzo[g]indeno[1,2-b]indole 12-oxides.
