The synthesis of the structure, 1, assigned to the anti-inflammatory natural product myrsinoic acid F is reported together with a means for preparing its Z-isomer 21. While neither of these compounds corresponds to the natural product, both of them are anti-inflammatory agents (as determined using a mouse ear edema assay) with congener 1 being notably more potent than the widely prescribed NSAID indometacin

A total synthesis of compound 3 from p-bromophenol is reported and thereby establishing that this, rather than its cyclodehydrated counterpart 1 (as postulated originally), is the correct structure of the natural product myrsinoic acid F. The biological evaluation of compound 3 in a mouse-ear edema assay established that it is a significantly more potentanti-inflammatoryagent than the NSAID indometacin

A formal synthesis of fumagillol, a congener of fumagillin that possesses varied biological activity, is disclosed. Initial attempts at preparing an allylic sulfide via an α-chloro sulfide met with failure. The successful route involves a carbonyl-ene reaction, one-pot stannyl cupration, methylation of resulting alkenyl copper and further Stille-coupling of the alkenyl stannane as the key steps.
