| titleOfInvention | Production of isocarbacyclins |
| abstract | PURPOSE: To produce isocarbacyclins, prostaglandin I 2 relative, industrially and advantageously by reacting a 4,4'-bisarylsulfonylisocarbacyclin with a reducing agent. n CONSTITUTION: A 4,4'-bisarylsulfonylisocarbacyclin (enantiomer or mixture in an arbitrary ratio) shown by formula I (R 1 is alkyl or alkenyl; R 2 and R 3 are trihydrocarbon silyl or group with O of OH to form acetal group; R 4 is H, methyl or vinyl; R 5 is alkyl, alkenyl or alkynyl which may contain O, phenyl, phenoxy, cycloalkyl, etc.; Ar is phenyl) is reacted with a reducing agent and optionally subjected to deprotecting reaction and/or hydrolysis to give an isocarbacyclin shown by formula II (R 11 are H, alkyl or alkenyl; R 21 and R 31 are H, trihydrocarbon silyl, etc.). n COPYRIGHT: (C)1991,JPO&Japio |
