Beteiligte Stoffe

Reaktionsschritte

Refer to Chart 36. The mixed formula-CC bis(THP ether) of the PGF2α compounds (Example 36, 1.5 g.) in 60 ml. of ethyl acetate are reduced at C5 -C6 by hydrogenation at about 25° C. in the presence of 200 mg. of 5% palladium-on-carbon with slightly over the theory for one equivalent of hydrogen. The solids are filtered off and the filtrate concentrated to yield the corresponding formula-CCXII bis(THP ether) of the PGF1α compounds having Rf 0.28 (TLC on silica gel in acetone-Skellysolve B (1:2)).
