General Description

2-(3,3-dimethylbutan-2-ylidene)-1,1-dimethylhydrazine, also known as UDMH, is a liquid chemical compound with a molecular formula of C6H16N2. It is a highly toxic and flammable material that is used as a rocket propellant due to its high energy density and stability. UDMH is also used as a fuel in industrial applications such as in gas turbines and power plants. It is a clear, colorless or pale yellow liquid with a sharp, ammonia-like odor. UDMH is a highly reactive chemical that must be handled with extreme care and caution due to its hazardous nature.

Stereoselective synthesis of δ-lactones from 5-oxoalkanals via one-pot sequential acetalization, tishchenko reaction, and lactonization by cooperative catalysis of samarium ion and mercaptan

By the synergistic catalysis of samarium ion and mercaptan, a series of 5-oxoalkanals was converted to (substituted) δ-lactones in efficient and stereoselective manners. This one-pot procedure comprises a sequence of acetalization, Tishchenko reaction and lactonization. The deliberative use of mercaptan, by comparison with alcohol, is advantageous to facilitate the catalytic cycle. The reaction mechanism and stereochemistry are proposed and supported by some experimental evidence. Such samarium ion/mercaptan cocatalyzed reactions show the feature of remote control, which is applicable to the asymmetric synthesis of optically active δ-lactones. This study also demonstrates the synthesis of two insect pheromones, (2S,5R)-2-methylhexanolide and (R)-hexadecanolide, as examples of a new protocol for asymmetric reduction of long-chain aliphatic ketones.
