Mild and chemoselective opening of lactones with sodium trimethylsilanolate in high yields and aprotic solvents is described. Kinetic studies demonstrate that the BAc2 mechanistic pathway is followed. Nucleophilic attack of silanolate onto the carbonyl of the lactone moiety is the rate-determining step. NaOH present as an impurity accelerates the reaction. The method was further applied to the base-sensitive and stable lactones derived from highly functionalized iridoid derivatives.
CARBOXYLATED PHOSPHATIDIC ACID ESTERS

, (2008/06/13)
Novel compounds of formula in which R1 and R2 are phospholipid fatty acid residues and A is an aliphatic and/or cycloaliphatic hydrocarbon chain optionally substituted by hydroxy and/or further carboxylic functions. The novel compounds are useful for making liposomes of enhanced stability and entrapping capacity.
