6 Purpose
Pivaloyl chloride is a very important acylating agent, mainly used as pharmaceutical intermediates, as the main raw material for the preparation of amides and many drugs in lipid phenol; currently used hydroxylamine hydroxylamine benzyl benzyl penicillin and cephalosporins, cefazolin production oxazoline, double pivaloyl adrenaline and other drugs. It is also a lot to do with the production of pesticide intermediates, such Chloropivaloyl chloride.
Chemical synthesis for the protection of the amino group, while increasing the steric effect, the location of a particular product is easily obtained.
