| titleOfInvention | Production of bicyclo(3.3.0)octane compound |
| abstract | PURPOSE: To efficiently obtain the titled compound, by treating a readily available 2-alkoxycarbonyl-3-substituted cyclopentanone as a raw material compound with an alkali metal hydride in an inert solvent and subjecting the resultant compound to intramolecular cyclization reaction. n CONSTITUTION: A cyclopentanone derivative expressed by formula I (R is 1W5C alkyl or 3W6C alkenyl; X is halogen; the double bond indicates the E-isomer, Z-isomer or E/Z mixture in any proportion), e.g. a compound expressed by formula II, etc., is treated with an alkali metal hydride, e.g. lithium hydride, etc., in an inert solvent to give a bicyclo[3.3.0]octane expressed by formula III, e.g. a compound expressed by formula IV, which is, together with a lithium halide, heat-treated in a polar inert solvent to afford the aimed bicyclo[3.3.0]octane expressed by formula V (A is H or COOR). n USE: An intermediate for prostaglandins. n COPYRIGHT: (C)1987,JPO&Japio |
