NEW ROUTES TO 1,1-DICHLORO-4-METYL-1,3-PENTADIENE

1,1,1-trichloro-2-hydroxy-4-methyl-pentene-3 (1b) was chlorinated to afford tri- and tetra-chlorinated compounds 2,3,4.Compounds 2 and 3 were transformed by reductive dechlorination into 1,1-dichloro-4-methyl-1,3-pentadiene.Another route starting from the same alcohol or its isomer was also developed.

Liebeskind-Srogl cross-coupling on γ-carboxyl-γ-butyrolactone derivatives: Application to the side chain of amphidinolides C and F

The synthetic approach for the C20-C29 and C20-C34 fragments of amphidinolide F and C was based on an original Liebeskind-Srogl cross-coupling reaction with a glutamic acid-derived building-block. Further highly diastereoselective reduction of the ketone was achieved by using an uncommon Ph3SiH/TBAF/HMPA system. The amphidinolide C side chain was built through a reductive elimination of chiral epoxide to install the stereogenic center at C29.
