An efficient synthesis of methyl (13S)-coriolate (S)-1b is accomplished by the palladium-catalyzed coupling of (1E,3S)-1-iodooct-1-en-3-ol [(S)-3] with methyl dec-9-ynoate (4) followed by selective reduction of the enyne (S)-2.

Natural 12-hydroxyheptadecatrienoic acid (12-HHT) with an S configuration was synthesised by a Suzuki-Miyaura coupling of C10-C17 iodo alcohol with C1-C9 vinylborane. The iodo alcohol was synthesised by utilising Sharpless asymmetric epoxidation of the corresponding trimethylsilyl alcohol. The method yielded more than 100 mg of 12-HHT. Similarly, syntheses of 5,6-dihydro- and 14,15-dehydro derivatives of 12-HHT, known as HHD and HHTE, respectively, were completed in a stereoselective manner.

A fully stereocontrolled synthesis of 3-oxacarbacyclin (3) and a formal synthesis of carbacyclin (2) are described. The syntheses are based on the conjugate addition-azoalkene-asymmetric olefination strategy. Its key features are (1) the stereoselective e

An asymmetric total synthesis of Prostaglandin E1 (5) has been achieved in a two-component coupling process. The chiral hydroxycyclopentenone 6 was readily available from furan with 96% ee. The key reaction step was a kinetic enzymatic resolution followed by an in situ inversion. A catalytic asymmetric reduction of the γ-iodo vinyl ketone 19 with the Corey CBS catalyst gave the ω-side chain 7 with >96% ee. Conjugate addition using the reaction with dilithiocyanocuprate followed by mild cleavage of the silyl protective groups and enzymatic hydrolysis of the methyl ester 22 gave (-)-PGE1 5 in high yield.

The addition of functionalized dialkylzincs to readily available β-stannylated or β-silylated unsaturated aldehydes in the presence of a catalytic amount of (1R,2R)-1,2-bis(trifluorosulfonamido)cyclohexane (8 mol percent) provides chiral allylic alcohols
