The effects of isopropyl substituents and molar concentration of diastereomeric esters toward the formation of nine-membered unsaturatedlactones, in the context of the synthesis of the intermediates of the antihypertensive drug aliskiren, have been studied. The effects of isopropyl substituents and molar concentration of diastereomeric esters toward the formation of nine-membered unsaturated lactones
A method of inhibiting parasitic activity is disclosed in which the biosynthesis, structure and/or function of the glycosyl phosphatidylinositol (GPI) anchor of said parasite may be affected by incorporating into said GPI anchor selected analogs of myristic acid containing various heteroatoms, substituents and unsaturated bonds, including ester-containing analogs, ketocarbonyl-containing analogs, sulfur-containing analogs, double bond- and triple bond-containing analogs, aromatic moiety-containing analogs, nitrated analogs and halogenated analogs.
