3-Alkyl-1,2-cyclopentanediones by Negishi cross-coupling of a 3-bromo-1,2-cyclopentanedione silyl enol ether with alkylzinc reagents: An approach to 2-substituted carboxylic acid γ-lactones, homocitric and lycoperdic acids

Negishi cross-coupling of the silyl-protected 3-bromoenol of 1,2-cyclopentanedione with primary and secondary alkylzinc reagents using Pd-catalysts affords 3-alkyl substituted 1,2-cyclopentanediones in good yield. The method was applied to obtain 3-methyl
μ-Oxo-Dinuclear-Iron(III)-Catalyzed O-Selective Acylation of Aliphatic and Aromatic Amino Alcohols and Transesterification of Tertiary Alcohols

A highly chemoselective and reactive μ-oxo-dinuclear iron(III) salen catalyst for transesterification was developed. The developed iron complex catalyzed acylation of aliphatic amino alcohols with nearly perfect O-selectivity, even when using activated esters, for which chemoselectivity is more difficult to control. In addition, O-selective transesterification of aromatic amino alcohols was achieved for the first time. The high activity of the iron complex enabled the use of sterically congested tertiary alcohols, including unprecedented tert-butanol.
A versatile scaffold for a library of liposidomycins analogues: A crucial and potent glycosylation step
Gravier-Pelletier, Christine,Ginisty, Maryon,Le Merrer, Yves
, p. 189 - 193 (2007/10/03)
A key step for the synthesis of a diazepanone scaffold dedicated to a library of MraY inhibitors is described. It involves the O-glycosylation of a conveniently protected L-serine by a D-ribofuranose derivative. High yield and selectivity were obtained.
