Abstract:
The Mn(III)-based oxidative cyclization of twenty-five N-aryl-2-oxocycloalkane-1-carboxamides is investigated. The reactions progress efficiently to give the desired spiro[cycloalkane-1,3′-indoline]-2,2′-diones in high to quantitative yields. The easy conversion of the carbonyl functional group of one of the indoline products, 1′-methylspiro[cyclo­hexane-1,3′-indoline]-2,2′-dione, is also demonstrated.

Abstract:
A polystyrene (PS)-based fibrous color dosimeter, comprising a color former based on 2-(phenylamino)-6-(dipentylamino)-3-methylspiro[9H-xanthene-9,3′-phthalide] (Black305) fluoran leuco dye and a 2-(4-methoxystyryl)-4,6-bis(trichloromethyl)-1,3,5-triazine (MBTT) photoacid generator, was developed for visual detection of X-ray doses of 15 Gy and higher. The composite fiber was produced by using a centrifugal spinning method, and the obtained composite fiber exhibited a stable and uniform morphology with a fiber diameter of 10 μm or less and had sufficient mechanical strength.

Abstract:
In the title compound, C18H18N2O3, the central pyrrolidine ring adopts a half-chair conformation. The furan ring is almost perpendicular to the oxindole system. Intermolecular C—H...O and N—H...N hydrogen bonds link the molecules into ribbons running along the b-axis direction.
