The above-prepared compound A29 and 1.1 equivalents of rhodamine 3-propionic acid were dissolved in ethanol, one equivalent of pyridine was added, and the reaction was carried out at 80 C. for 4 hours. After the reaction was completed, the mixture was cooled to room temperature to precipitate a yellow solid, which was filtered by suction and used as a filter cake. After washing with dilute hydrochloric acid, washing with water, infrared drying, and recrystallization from ethanol gave a yellow solid with a yield of 81%.

General procedure: To thiazolidine-2-thiones (1.0 equiv.) in THF (5.5 mL/mmol), 60% NaH dispersion in mineral oil (1.2 equiv.)was slowly added at 0 C. The reaction mixture was stirred for 15 min at 0 C before acetyl chloride (1.2 equiv.)was added dropwise. The reaction mixture was stirred for 30 min at 0 C, upon which it was warmed to roomtemperature and allowed to stir for another 2 h. The reaction was quenched with saturated NH4Cl (3 mL/mmol)and the layers were separated. The aq. layer was extracted with EtOAc (2 x 4 mL/mmol) and the combinedorganic layers were dried (Na2SO4),filtered, and concentrated in vacuo. The crude product was purified bycolumn chromatography on silica (hexanes/EtOAc 8:2) to afford the title compounds as yellow oils.
