Synthesis of 4-L-Valine-6-L-Threonine-, 4-L-Isoleucine-6-L-Threonine-, 4-L-Leucine-6-L-Threonine-, 4-L-Valine-, and 4-L-Isoleucinebradykinin and Their O-Acetyl Compounds.

The synthesis and some of the pharmacological properties of [4-L-isoleucine]-oxytocin and [4-L-leucine]-oxytocin.

The Electrochemical Behavior of 4 , 4 ' - Azopyridine - l , l ' - Dioxide

The electroreduction of 4 ,4 ' -azobispyr idinel , l ' -d ioxide (APDO) in dimethyl formamide solutions was studied by polarography, cyclic vol tammetry, controlled potential coulometry, and electron spin resonance, Voltammetric reduction showed two well-defined, reversible one-elect ron transfers. Coulometric reduction at a potential corresponding to the plateau of the first wave gave evidence...

N-[(2S)-4-Chloro-2-(l-menth­yloxy)-5-oxo-2,5-dihydro­furan-3-yl]-l-valine

The title compound, C(19)H(30)ClNO(5), was obtained by the tandem asymmetric Michael addition-elimination reaction of (5S)-3,4-dichloro-5-(l-menth-yloxy)furan-2(5H)-one and l-valine in the presence of potassium hydroxide. The furan-one unit is approximately planar (r.m.s. deviation = 0.0204 Å) and the six-membered cyclo-hexane ring adopts a chair conformation. The crystal structure is stabilize...

Automotive components present unique challenges in reliability, security, performance and cost. Consolidation of different functions in multi-purpose units drives up complexity, and raises not only reliability concerns, but also the issue of liability for sub-component suppliers. It is of foremost importance to guarantee reliability and security right from the start when designing such systems....
