The presence of NMP (4–9 equiv.) clearly improves the yield and the chemoselectivity of the Cu-catalyzed alkylation of organomagnesium reagents. Thus, secondary and tertiary alkylmagnesium chlorides were used successfully for the first time in such

A highly functionalized precursor of (−)-4-deoxygigantecin possessing six stereogenic centers has been prepared in 14 steps from tridecanal. The key steps are (i) enantioselective aldolization, (ii) diastereoselective C-glycosylation and (iii) dias

4-Hydroxy-5-amino-6-phenyl-4-hexanolide has been synthesized under its cyclized form (lactone 5) from a very inexpensive chiral starting material, L-glutamic acid. The key steps were an original reduction of carbonyl of a ketone with n-Bu3SnH in the

A new annonaceous acetogenin, reticulatamol 1, is described. In order to confirm its structure, its total synthesis has been performed, using as a key step a radical coupling reaction between an alkyl iodide and an enone, followed by an original redu
