The optically active 6a-carbaprostaglandin I2 (2), a stable mimic of natural prostacyclin (1), was synthesized from the lactone 4 or the hydroxy acid 5, which were general synthetic intermediates for natural prostaglandins.

The products from the Prins reaction of formaldehyde and (+/-)-7,7-dichloro-4β-trimethylsilylbicyclohept-3-en-6-one were isolated and characterized.The optimum conditions were found for the production of the isomeric 2β-acetoxy-6,6(7,7)-dichlorobicyclohept-3-en-7(6)-ones and 2β-acetoxymethyl-3α-acetoxy-6,6(7,7)-dichlorobicyclohept-3-en-7(6)-ones and also (1R,2S,5R,6S,10R)-3,3-dichloro-4-oxo-10-hydroxy(acetoxy)-8-oxatricyclo2,5>undecanes, suitable for the subsequent synthesis of modified prostanoids.An effective scheme for the synthesis of (+/-)-carbacyclin was worked out on the basis of the monoacetates of a series of bicycloheptenones through the corresponding 2β-acetoxymethyl-3α-acetoxybicyclooctan-7-ones.
A NEW SYNTHESIS OF (+)-6a-CARBAPROSTAGLANDIN I2 EMPLOYING YEAST REDUCTION OF A β-KETO ESTER DERIVED FROM cis-BICYCLOOCTANE-3,7-DIONE AS THE KEY-STEP

(+)-6a-carbaprostaglandin I2 (carbacyclin), a stable mimic of prostaglandin I2 (prostacyclin), was synthesized by utilizing the kinetic resolution of (+/-)-2-ethoxycarbonyl-7,7-ethylenedioxybicyclooctan-3-one in the course of its yeast reduction as
