Abstract

The title compound, C29H35NO6.0.334C3H8O, a novel chiral N-(fluoren-9-yl­methyl­oxyxcarbon­yl) precursor, crystallizes with two independent carbamate (M) mol­ecules and propan-2-ol solvent mol­ecules in the unit cell. Its crystal structure has been determined from barely adequate data obtained from a multi-fragment needle crystal. In the crystal, N—H⋯O hydrogen bonds link M mol­ecules related by translation along the a axis into two independent chains. The ordered solvent mol­ecule, having a partial occupancy of 0.334, is attached to one independent M mol­ecule through O—H⋯O hydrogen bonds. The crystal packing exhibits weak inter­molecular C—H⋯O inter­actions and voids of 270 Å3 filled with randomly disordered solvent mol­ecules which were handled using the SQUEEZE methodology.
