Active methylene compounds reacted readily with stable hydrate 2-diethoxyphosphoryl-2,2-difluoroethane-1,1-diol to afford a range of activated alkenes bearing the difluoromethylenephosphonate group, a useful motif in the synthesis of phosphate ester mimics of biological interest. Wadsworth-Horner-Emmons reactions were employed using modified Rathke conditions for the syntheses of alkenoates, an alkenoic acid and a vinyl sulfone, while a Henry reaction followed by E1cB dehydration afforded an enedioate and a nitroalkene. A vinyl sulfoxide was less straightforward to synthesise and dephosphorylation to a difluoromethyl congener accompanied attempts to force the reaction to completion.

Phosphorylated cyclopropanes in the synthesis of α-alkylidene-γ-butyrolactones: Total synthesis of (±)-savinin, (±)-gadain and (±)-peperomin e

Phosphorylated cyclopropanes, generated via the Rh(ii)-catalysed intramolecular cyclopropanation of α-(diethoxyphosphoryl)acetates, have been found to be useful precursors in the synthesis of α-alkylidene-γ-butyrolactones. These cyclopropyl intermediates undergo regioselective reductive ring-opening and subsequent Horner-Wadsworth-Emmons olefination to complete the synthesis. Total syntheses of (±)-savinin and (±)-gadain, as well as the first total synthesis of (±)-peperomin E, are all described using this method.

The absolute configurations of the three unknown chiral centers in vinylamycin were predicted according to the structural comparison with microtermolide A and rakicidin A, and then total syntheses of vinylamycin were applied to determine the three unknown chiral centers as 14R, 15R, and 16S.

, p. 23 - 29 (2007/10/02)
The first synthesis of mycinolide-V (1) is reported. 1 is the aglycon of mycinamycin-V, a 16-membered macrolide antibiotic.The synthesis starts from a C-3/C-9 segment, which has been extended to a C-1/C-10 building block, and subsequently condensed with a C-11/C-17 segment.
