A method for the synthesis of specialized pro-resolving mediators, structural isomers thereof and analogs thereof is disclosed herein. The method comprises reacting a compound of the formula (I): (I) wherein R1 is alkyl(C≤12), cycloalkyl(C≤12), alkenyl(C≤12), alkylidene(C≤12), alkynyl(C≤12), aryl, aralkyl, heteroaryl or heteroaralkyl; and X1, X2 and X3 are each independently hydroxy or OP, wherein P is a hydroxy protecting or hydroxy activating group; with a reducing agent under conditions sufficient to produce a compound of the formula (II): (II) wherein: R1, X1, X2 and X3 are as defined above. Novel protectins, more specifically novel structural isomers and analogs of PD1 and PDX are also disclosed.
Stereoselective synthesis of the C13-C28 subunit of (-)-laulimalide utilizing an α-chlorosulfide intermediate

A stereoselective route to the C13-C28 subunit of (-)-laulimalide is described. l-Tartaric acid is the source of the hydroxy groups at C19 and C20. An α-chlorosulfide is employed as the key intermediate for the creation of the C17-C18 bond and the C16-C17 double bond was introduced using the Mislow-Braverman rearrangement and Hutchin's dexoxygenation with concomitant double bond transposition reaction. The C15 and C23 stereogenic centers were created using catalytic asymmetric reactions. The trisubstituted and trans-disubstituted alkenes were created stereoselectively by taking advantage of ring-closing metathesis and the Julia-Kocienski olefination reaction, respectively.
