1′,6-Dimethyl-4′-phenyl­dispiro­[1-benzopyran-3(4H),3′-pyrrolidine-2′,3′′-indoline]-2,2′′-dione

In the title compound, C(27)H(24)N(2)O(3), the five-membered pyrroldine ring adopts an envelope conformation (with the N atom in the flap position) and the six-membered pyran-one ring of the coumarine ring system adopts a slightly distorted boat conformation. The oxindole unit makes dihedral angles of 89.7 (1) and 25.6 (1)°, respectively, with the pyrrolidine ring and the coumarin ring system. ...

3′,6′-Bis(ethyl­amino)-2′,7′-dimethyl-2-{[2-[(E)-3,4-methyl­enedioxy­benzyl­idene­amino]eth­yl}spiro­[isoindoline-1,9′-xanthen]-3-one

The title compound, C(36)H(36)N(4)O(4), was prepared as a spiro-lactam ring formation of the rhodamine dye for comparison with a ring-opened form. The xanthene ring system is approximately planar [r.m.s. deviations from planarity = 0.023 (9) Å for the xanthene ring]. The dihedral angles formed by the spiro-lactam and 1,3-benzodioxole rings with the xanthene ring system are 86.8 (1) and 74.3 (1)...

[(2-{[3′,6′-Bis(ethyl­amino)-2′,7′-dimethyl-3-oxospiro­[1H-isoindole-1,9′-9H-xanthen]-2-yl}eth­yl)amino­meth­yl]phenol

The title compound, C(35)H(38)N(4)O(3), was prepared as a spiro-lactam ring formation of rhodamine dye for comparison with a ring-opened form. The xanthene ring system is approximately planar. The dihedral angles formed by the spiro-lactam and phenol rings with the xanthene ring system are 85.7 and 109.4°, respectively. Each of the mol-ecules in the crystal structure contains one intra-molecula...
