REDUCTION OF KETONIC CARBACYCLIN INTERMEDIATES
Process for the production of alpha -hydroxy-bicyclo[3.3.0]octane derivatives of formula (I), where A is the double-bound residue -O-X-O-, X having the notation of a straight or branched-chain alkalin with 1-7 C atoms or the residue =CH-(CH2)3-COOR', =CH-CH2-O-CH2-COOR' or = CH-(CH2)3-O-CH...

Summary: | Process for the production of alpha -hydroxy-bicyclo[3.3.0]octane derivatives of formula (I), where A is the double-bound residue -O-X-O-, X having the notation of a straight or branched-chain alkalin with 1-7 C atoms or the residue =CH-(CH2)3-COOR', =CH-CH2-O-CH2-COOR' or = CH-(CH2)3-O-CH2-CH2-COOR', with R' as C1-C7 alkyl; R is the residue (a), R'' having the notation of a hydrogen or phenyl, or the residue - SiR1, R2, R3, whereby R1, R2 and R3 can be the same or different and a straight or branched-chain alkyl group with 1-7 C atoms or phenyl; B is a trans-CH=C(X), with X as hydrogen or bromine, whereby the trans configuration relates to the C network; and D is an alkyl group with 1-10 C atoms, an alkenyl group with 1-10 C atoms or an alkinyl group with 1-10 C atoms. This process is characterized in that keto-bicyclo[3.3.0]octane derivatives of formula (II) are reduced in the presence of Cer-III salts. |
