1-O-Alkyl (di)glycerol ethers synthesis from methyl esters and triglycerides by two pathways: catalytic reductive alkylation and transesterification/reduction
esters, monoglycerides or oleic sunflower refined oil, the corresponding 1-O-alkyl (di)glycerolethers were obtained in both high yields and selectivity by two different pathways. With methyl esters, a reductivealkylation with (di)glycerol was realized under 50 bar hydrogen pressure in the presence of 1 mol% of Pd/C and an acid co-catalyst. A second two step procedure was evaluated from methyl esters

(2-PGE2-G) analogs were designed and synthesized to aid in the characterization of a putative prostamide receptor. Our design incorporates the electrophilic isothiocyanato and the photoactivatable azido groups at the terminal tail position of the prototype. Stereoselective Wittig and Horner–Wadsworth–Emmons reactions install the head and the tail moieties of the PGE2 skeleton. The synthesis is completed using
