A totalsynthesis of d1-coriolin has been accomplished starting from 1,3-cyclooctadiene, in which a rational and efficient introduction of various functional groups to the synthetic intermediate, 7-endo-t-butyldimethylsilyloxybicyclo[3.3.0]-oct-8-en-2-one, is involved.
1,2-CARBONYL TRANSPOSITION OF<i>CIS</i>-BICYCLO[3.3.O]OCTAN-2-ONE TO ITS 3-ONE SKELETON: APPLICATION TO SYNTHESES OF<i>dl</i>-HIRSUTIC ACID AND<i>dl</i>-9(0)-METHANOPROSTACYCLIN
A synthetic route to dl-hirsutic acid and an improved synthesis of dl-9(0)-methanoprostacyclin, both of which employ the 1,2-carbonyl transposition as a key step, are described.
