tert-Butyl (2S,3R,4R)-7′-bromo-4-methyl-2′,5-dioxo-4,5-dihydro-3H-spiro[furan-2,3′-indoline]-3-carboxylate

In the title compound, C17H18BrNO5, the furan ring has an envelope conformation with the carboxylate substituted C atom as the flap. The planar indoline ring is inclined to the mean plane of the furan ring by 87.5 (2)°. In the crystal, molecules are linked by N—H...O and C—H...O hydrogen bonds formi...

Description
Summary:In the title compound, C17H18BrNO5, the furan ring has an envelope conformation with the carboxylate substituted C atom as the flap. The planar indoline ring is inclined to the mean plane of the furan ring by 87.5 (2)°. In the crystal, molecules are linked by N—H...O and C—H...O hydrogen bonds forming chains propagating along the a-axis direction.
