Abstract
The stereospecific alkylation of a novel 3-endo-protected hydroxyl-tricyclo[3,2,0,0.sup.2,7 ]heptan-6-one is described using a range of lithium-, copper or magnesium-containing organometallic reagents. This reaction provides a 5-endo-protected hydroxyl-bicyclo[2,2,1]-heptan-2-one system from which prostaglandin compounds of the F series having a protecting group at the 9-position hydroxyl group may readily be obtained by a sequence of reactions.
