Spectral assignments and reference data formation and structure elucidation of two novel spiro[2H-indol]-3(1H)-ones

Original language description

The molecular structures of two byproducts 1,1''-diphenyl-3',4'-dihydrodispiro[indole-2,2'-furan-5',2''-indole]-3,3''(1H, 1''H)-dione (3) and 1,5'-diphenyl-4,5-dihydro-3'H-spiro[indole-2,2'-pyrano[3,2-b]indol]-3(1H)-one (4), which accompanied the rearrangement of 3-hydroxy-3-methyl-1-phenylquinoline-2,4(1H,3H)-dione (1) to 2-hydroxy-2-methyl-1-phenyl-1,2-dihydro-3H-indol-3-one (2), have been elucidated by NMR, MS, and X-ray diffraction.

Czech description

Struktura dvou vedlejších produktů, 1,1''-difenyl-3',4'-dihydrodispiro[indol-2,2'-furan-5',2''-indol]-3,3''(1H, 1''H)-dionu (3) a 1,5'-difenyl-4,5-dihydro-3'H-spiro[indol-2,2'-pyrano[3,2-b]indol]-3(1H)-onu (4), které vznikají při přesmyku 3-hydroxy-3-methyl-1-fenylchinolin-2,4(1H,3H)-dionu (1) na 2-hydroxy-2-methyl-1-fenyl-1,2-dihydro-3H-indol-3-one (2), byla stanovena pomocí NMR, hmotnostní spektrometrie a rentgenové difrakční analýzy.
