Ethyl glutarate

The substituent effect of 10,10 -positions of bis[2-(9-anthryl)ethyl] glutarates 353a-e, which have more flexible chains, was investigated by irradiation with 350-nm light in dilute (10-4 M) deoxyganated benzene [349], The quantum yields for the dimerization (dimer) falls with the steric bulk of the substituents. 

JH III (34), the third juvenile hormone, is of course produced from three molecules of mevalonic acid (35) in the normal way]. Recent studies have provided support for these schemes by demonstrating that 3-hydroxy-3-ethyl-glutaric [c/. (26)], homomevalonic (27), and mevalonic acid (35) can be synthesized by crude enzymes isolated from the corpora allata of Manduca sexta ... 

For the synthesis of lobelanidine (486), ethyl glutarate is condensed with acetophenone in the presence of sodamide and the resulting 1 7-dibenzoylheptadione-2 6 (LIX) treated with ammonia at 100°. The product, however, is not the expected dihydropyridine derivative (LX) but... 

This phenomenon was observed at the resolution of racemic a-phenylethylamine (PEA) using (R)-N-(l-phenyl-ethyl)-glutaric acid ((R)-PEGA) as resolvong agent. From acetone was crystallized diastereomeric salt containing (S)-PEA with ee 58%. If is added an equivalent of carbamide to the mixture the enantiomeric excess of the isolated (S)-PEA was 90%. ...
