5-Exo-phenyl-2,3-dioxabicycloheptane (4c) was synthesized as a model compound of prostaglandin endoperoxide (PGH) to mimic the bioconversion of PGH into thromboxane (TX).The reaction of (4c) with various electron transfer reagents was investigated.With the aid of a catalytic amount of ferrous ion, (4c) was successfully converted into the thromboxane B (TXB) skeleton.

Reaction of 1,3-dibromo-4-phenylcyclopentane (23), prepared from 4-hydroxycyclopent-2-en-1-one (10) in a stereocontrolled manner, or its stereoisomer 24 with anhydrous hydrogen peroxide in the presence of silver trifluoroacetate in ether gave 1-phenyl-2,3-dioxabicycloheptane (25) mainly as a rearranged product.The expected 5-phenyl-2,3-dioxabicycloheptane (8) and phenylcyclopentenyl hydroperoxides 26 and 27 were also formed in this reaction.An authentic sample of endoperoxide 8 was prepared by using peroxide transfer reaction between bis(tri-n-butyltin)peroxide and bistriflate of cis-diol 35.The stereochemistry of the endoperoxide 8 and related compounds in this series was confirmed by correlation with the data from X-ray crystallographic analysis of the diacetate of diol 21 obtained from endoperoxide 8 by stannous chloride reduction.

Conversion of prostaglandin endoperoxide model compound (1) into the thromboxane B ring system (6a) and (7a) was achieved with the aid of the ferrous ion.
