| titleOfInvention | Method for splitting of racemic (1sr, 2 rs, 5r, 6rs)-bicyclo(3 |
| abstract | This invention relates to fine organic synthesis, in particular to the resolution of racemic (1SR, 2RS, 5SR, 6RS) -6H4rooio (3.3.0) oKTaH diol form I BUT gas-1 to obtain (IS, 2R, 5S, 6R) - 2,6-flH-acetoxy-bicyclo (3.3.0) octane of the formula II n3c- (o) s-oh II no-c (o) -cn3 and (1R, 2S, 5R, 63) -dicyclo (3.3.0) -Octane-2-diol f-ly III, non III n it can be used for the synthesis of optically active prostaglandins and their derivatives. In order to increase the yield and increase the enantiomeric excess of separable optical antipodes (1SR, 2RS, 5SR, 6RS) -6n-cyclo (3.3.0) octane-2, 6-diol is treated with 2,2,2-trichloroethyl acetate at 20 -40 ° C in the presence of pyridine or triethanolamine in anhydrous tetrahydrofuran. As an enzyme, lipases of animal origin are used, preferably crude lipase of porcine pancrease as a preparation. 1 hp f-ly. CO with Os 00 O o 00 SP |
