| titleOfInvention | Dihydropyranopyrazolidine derivative and its preparation |
| abstract | NEW MATERIAL:A 1,2-diphenyl-dihydropyrano[2,3-c]pyrazolidine derivative of formula I (X 1 , 2 are H, halogen, lower alkyl, lower alkyloxy, or hydroxyl, provided that one of X 1 and X 2 is H). n EXAMPLE: 1,2-Diphenyl-3-oxo-5-hydroxy-6,6-dimethyl-5,6-dihydropyrano[2,3-c]- pyrazolidine. n USE: Drug having antiphlogistic and blood platelet coagulation activities. n PROCESS: The compound I is prepared by reacting a compound II (X is H, halogen, lower alkyl, lower alkyloxy, or OH), e.g. 1,2-diphenyl-3,5-dioxo-(2',3'-dioxo-3'- methyl)-butyl-pyrazolidine, with a base such as NaOH, in a solvent such as water or methanol, at 0W100°C. The compound II is novel, and can be obtained by reacting a compound III with a peroxide. n COPYRIGHT: (C)1980,JPO&Japio |
