The intermediate containing vic-diol and enal functional groups was prepared via the oxidation of the γ,δ-epoxy alcohol followed by the epoxide ring opening in one pot.. The C11-aldehyde in the resulting enal was converted to the trans iodo-olefin by reaction with TMSC(N2)Li and subsequent hydrozirconation using in situ generated Cp2Zr(H)Cl followed by iodination. Article Title: Synthesis of resolvin E3 via palladium-catalyzed addition of AcOH to vinyl epoxy alcohols. Article Snippet: (18R)and (18S)-stereoisomers of resolvin E3 (RvE3), potent anti-inflammatory mediators, were synthesized stereoand enantioselectively through the Wittig reaction of the carbonate of 6R,7Rand 6R,7Sdihydroxynona-2E,4E-dienal, a C12–C20 part, with the phosphonium salt corresponding to the C1–C11 part.. The stereoisomeric carbonate was prepared by the Swern oxidation of 3-(AcO)-6R,7Ror 3-(AcO)6R,7S-(dihydroxy-carbonate)-4-nonen-1-ol followed by the spontaneous elimination of the AcO group in one pot.. The (6R,7R)-(dihydroxy-carbonate)-alcohol for (18R)-RvE3 was, in turn, provided by stereoselective epoxidation of 9-(TBS-oxy)nona-4Z,6E-dien-3R-ol with m-CPBA and the subsequent Pd-catalyzed addition of AcOH to the resulting syn vinyl epoxy alcohol followed by carbonate formation of the vic-syn-diol and TBS desilylation. Article Title: Stereoselective ozonolysis of TMS-substituted allylic alcohol derivatives and synthesis of 14R,15S- and 14S,15S-diHETE. Article Snippet: Ozonolysis of TMS-substituted olefins produces α-carbonyl TMS peroxides without cleavage of the CvC bond.. Herein, stereochemistry in the ozonolysis was studied using silyl derivatives of (E)and (Z)-(1-TMS) alk-1-en-3-ols.. The (E)-isomers afforded the anti-3-siloxy-2-(TMS-oxy)aldehydes as the major stereoisomer (anti/syn = 3–9 : 1) after reductive work-up with Ph3P. Article Title: Total Synthesis of Resolvin D5. Article Snippet: Resolvin D5 (RvD5) is a metabolite of docosahexanoic acid with anti-inflammatory activity that has not yet been thoroughly investigated because of its low biological availability.. A synthetic route to optically active RvD5 was developed by assembling the C1–C10 aldehyde, C11–C13 phosphonium salt, and C14–C22 aldehyde building blocks.. The aldehyde fragments were prepared by Sharpless asymmetric epoxidation of corresponding racemic (E)-1-TMS-1-alken-3-ols followed by reaction of the TBS ethers of the resulting epoxy alcohols with Et2AlCN, and DIBAL reduction of the (E)-1-cyano-1-alken-3-ol derivatives. Article Title: Stereocontrolled Synthesis of Resolvin D4. Article Snippet: The stereoselective synthesis of resolvin D4 (RvD4) was achieved using the Wittig reaction of the C1−C10 dienal with the known C11−C22 phosphonium salt.. The (S,E)-enantiomer (S)-10, corresponding to the C1−C8 part, was synthesized in 95% ee by the asymmetric transfer hydrogenation reaction of the corresponding acetylenic ketone followed by Red-Al reduction.. Sharpless epoxidation of this alcohol using Ti(O-i-Pr)4/L-(+)-DIPT as a catalyst produced anti epoxy alcohol with >99% ee as the sole product in 82% yield.
