Enzymes and microorganisms were screened for the enantioselective hydrolysis of (±)-1-acetoxy-2,3-dichloropropane (1) which is convertible to epichlorohydrin. Pancreatin and steapsin from hog pancreas were found to hydrolyze (±)-1 asymmetrically to give (S)-1 of 90% enantiomeric excess (e.e...
1,2-Dibromo-3-chloropropane (DBCP) was used as a soil fumigant and nematicide on about 40 crops in the United States until 1977. Long-term exposure to DBCP in humans has adverse effects on the male reproductive system including reduced sperm counts and hypogonadism, which are reversible w...
The addition of water under mild acidic conditions gives 3-hydroxypropionaldehyde with high selectivity. Preferentially buffer solutions with a pH 4-5 or weak acidic ion exchange resins are used as catalysts. Further hydrogenation of this aqueous solutions gives 1,3-propanediol. There is an alternati...
For 2,2-dichloropropane and 1,1-dichloropropane elimination of HCl occurs but for 1,1-dichlorobutane, -pentane and -hexane partial hydrolysis followed by elimination of HCl givesE,E-,E,Z- andZ,Z- isomers of the dialk-1-enyl ethers and fully assigned13C NMR data are presented for these....
