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.

Process for the preparation of unsaturated geminal dihalogen compounds

The invention relates to a new process for preparing unsaturated geminal dihalogen compounds. More particularly, the invention concerns a process for preparing compounds of the formula (I) STR1 wherein X is halogen, R1 is a straight or branched chained alkenyl group having 2 to 6 carbon atoms, by clearing the corresponding 1-substituted 2,2,2-trihaloethylesters.

Electrochemical synthesis of insecticide intermediates

1,1,1-Trihalo-4-methylpentenes, carrying 2-substituents selected from those conjugate bases of Bronsted acids which are leaving groups in beta eliminations, are reduced electrochemically to 1,1-dihalo-4-methylpentadienes, intermediates in the synthesis of pyrethroid insecticides.
