Triply-convergent synthesis of a homochiral 3,3-dimethyl, 15-cyclohexyl prostacyclin analog
Allylic bromocuprate reagent 13b undergoes synfacial SN2′ addition to homochiral allyl ammonium salt 14 to provide vinyl sulfone 15 as a single stereoisomer. Addition of homochiral acetylenic anion 18 to vinyl sulfone 17 smoothly provides the bicyclic sulfone 19 which is further transformed to prost...

Summary: | Allylic bromocuprate reagent
13b
undergoes synfacial SN2′ addition to homochiral allyl ammonium salt
14
to provide vinyl sulfone
15
as a single stereoisomer. Addition of homochiral acetylenic anion
18
to vinyl sulfone
17
smoothly provides the bicyclic sulfone
19
which is further transformed to prostacyclin analog
22
. Analog
22
was only a weak inhibitor of platelet aggregation having an IC
50 of 0.48 μM.
