Improved synthesis and low-temperature performance of a series of saturated α-branched fatty acids

Five saturated α-branched fatty acids, also known as Guerbet acids, including α-propylhexyl acid (G 1 ), α-butylhexyl acid (G 2 ), α-propyloctyl acid (G 3 ), α-butyloctyl acid (G 4 ), and α-hexyloctyl acid (G 5 ), were synthesized in high yields by four-step reaction. Colorless, almost odorless, and oily products were obtained with high purity, whose structures were confirmed by GC, 1H/13C NMR, and ESI-MS characterization. G 1, G 3, and G 4 had pour points lower than -60 °C, while G 2 and G 5 showed higher pour points (-42 °C and 6 °C, respectively) because of their molecular symmetry. Considering the low-temperature properties, G 1, G 3, G 4, and even G 2 held great potential applications in the lubricant and oilfield.

Microwave assisted hydrolysis of Meldrum's acid derivatives and decarboxylation of derived malonic acids

Microwave induced hydrolysis of alkyl Medrum's acids and decarboxylation of derived malonic acids using poly-4-vinylpyridine as a catalyst gives high yields of carboxylic acids in a short time.

1,1-Alkanediol dicarboxylate linked antibacterial agents

Useful antibacterial agents in which a penicillin and/or a beta-lactamase inhibitor are linked via 1,1-alkanediol dicarboxylates are of the formula STR1 where A is the residue of certain dicarboxyic acids, R3 is H or (C1 -C3), n is zero or 1 such that when n is zero R is P or B and R1 is the residue of certain esters, H or a salt thereof; and when n is 1, one of R and R1 is P and the other is B, and P is STR2 where R2 is H or certain acyl groups, and B is the residue of a beta-lactamase inhibiting carboxylic acid; a method for their use, pharmaceutical compositions thereof and intermediates useful in their production.
