parent carboxylic acid. When evaluated in vivo, the methyl phosphinic acid analogue (4b) produced a boneanabolic response in rats, returning bone mineral volume (BMV) [corrected], to intact levels in the distal femur in the ovariectomized rat (OVX) model. These results suggest that prostaglandins of this class may be useful agents in the treatment of diseases associated with bone loss.
Systems and methods to produced branched aliphatic alcohols are described. Systems may include a dehydrogenation-isomerization unit, an olefin dimerization unit, an olefin isomerization unit, a hydroformylation unit, a dehydrogenation unit, a hydrogenation unit and/or combinations thereof. Methods for producing branched aliphatic alcohols may include isomerization of olefins in a process stream. The isomerized olefins may be hydroformylated to produce aliphatic alcohols. After hydroformylation of the aliphatic alcohols, unreacted components from the hydroformylation process may be separated from the aliphatic alcohols products. The unreacted components from the hydroformylation process may be recycled back into the main process stream or sent to other processing units. Addition of multiple streams to the units may be performed to control reaction conditions in the units.

The synthesis and stability of anionic, neutral and cationic gadolinium complexes based on tetraazaphosphinic acid ligands is compared: lipophilic anionic complexes show biliary rather than renal clearance.

The reactions of diethyl ethylphosphonite with 3-O-acetyl-5-deoxy-5-iodo-1,2-O-isorpopylidine-α-d-xylofuranose (Ia) or 3-O-benzoyl-5-deoxy-5-iodo-1,2-O-isopropylidene-α-d-xylofuranose(Ib) afforded IIa or IIc, respectively. Similarly, using diethyl butylphosphonite in place of diethyl ethylphosphonite, IIb and IId were obtained. Treatment of IIb with methanolic sodium methoxide gave 5-deoxy-1,2-O-isopropylidene-5-(methoxybutylphosphinyl)-α-d-xylofuranose together with a small amount of 5-(3-O-cyclo-butylphosphinate)-5-deoxy-1,2-O-isopropylidene-α-d-xylofuranose(VII). Compound VII was also obtained from the reaction of 5-deoxy-5-iodo-1,2-O-isopropylidene-α-d-xylofuranose(VIII) and diethyl butylphosphonite. The reaction of IIa or IIc with sodium dihydrobis(2-methoxyethoxy)aluminate gave 5-deoxy-5-(ethylphosphinyl)-1,2-O-isopropylidene-α-d-xylofuranose(IIIa). Similarly, 5-(butylphosphinyl)-5-deoxy-1,2-O-isopropylidene-α-d-xylofuranose(IIIb) was obtained from IIb, IId, VI, and VII. Hydrolysis of IIIa and IIIb with sulfuric acid gave 5-deoxy-5-(ethyl-phosphinyl)-(IVa) and 5-(butylphosphinyl)-5-deoxy-d-xylopyranose(IVb), respectively. Acetylation of IVa and IVb with acetic anhydride in pyridine gave the corresponding O-acetates Va and Vb.
