HCID 461954301-(diphenylmethyl)-5',6',7',8'-tetrahydrospiro[indole-3,3'-naphtho[2,3-b]furan]-2(1'H)-one

Procedure

Following the procedure as described in EXAMPLE 2 and making non-critical variations using 1-(diphenylmethyl)-3-(3-hydroxy-5,6,7,8-tetrahydronaphthalen-2-yl)-1,3-dihydro-2H-indol-2-one to replace 1-(diphenylmethyl)-3-(2-hydroxy-4-methoxy-5-methylphenyl)-1,3-dihydro-2H-indol-2-one, 1-(diphenylmethyl)-5′,6′,7′,8′-tetrahydrospiro[indole-3,3′-naphtho[2,3-b]furan]-2(1H)-one was obtained (81%) as a colorless solid: 1H NMR (300 MHz, CDCl3) δ7.37-7.32 (m, 10H), 7.17-7.14 (m, 1H), 7.07 (s, 1H), 7.05-6.94 (m, 2H), 6.67 (s, 1H), 6.52 (d, J=7.6 Hz, 1H), 6.33 (s, 1H), 4.96 (d, J=8.9 Hz, 1H), 4.69 (d, J=8.9 Hz, 1H), 2.73 (br s, 2H), 2.54 (br s, 1H), 1.72-1.70 (m, 4H); MS (ES+) m/z 457.9 (M+1).
