| titleOfInvention | Tetrahydronaphthalene derivative |
| abstract | NEW MATERIAL:A tetrahydronaphthalene derivative expressed by formula I (R 1 and R 2 are lower alkoxy; n is 0 or 1). n EXAMPLE: 2Z-(2-Hydroxyethylidene)-5,8-dimethoxy-1,2,3,4-tetrahydrofuran. n USE: A medicine and raw material capable of synthesizing bicyclic-hydroxyketones expressed by formula II which are synthetic intermediate for 4- demethoxydaunorubicin which is a nonnatural type anthracyclin based antibiotic substance attracting attention by a wide carcinostatic spectrum and powerful carcinostatic activity in a short step. n PREPARATION: A homoallyl alcohol expressed by formula III is acetylated to give a compound expressed by formula IV, which is then converted into a dienol acetate expressed by formula V. The resultant dienol acetate expressed by formula V is then subjected to 1,4-hydrogenation reaction to afford an allyl acetate expressed by formula VI, which is further hydrolyzed to give the compound expressed by formula I (n is 0). The resultant compound expressed by formula I (n is 0) is then subjected to asymmetric epoxidation reaction to afford the compound expressed by formula I (n is 1). n COPYRIGHT: (C)1987,JPO&Japio |
