Spiro[4H-pyran-4,10′(4’H)-[6H]pyrimido[2,1-c][1,4]thiazepine]-2′-carboxylic acid, 2,3,5,6,7′,8′-hexahydro-3′-hydroxy-4′-oxo-, ethyl ester, 9′,9′-dioxide: To a stirred yellow mixture of intermediate 19/24 (0.1942 g, 0.50 mmol) intermediate 18 (0.208 g, 0.62 mmol) in DMF (5 mL) wad added Cs2CO3 (0.332 g, 1.02 mmol) at once at room temperature. After 24 h, the reaction mixture was diluted with Et2O (50 mL), washed with water (2×10 mL), brine (10 mL), dried (Na2SO4), filtered and concentrated to give colorless paste which was used in the subsequent step without purification.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
