Dithiomalonic acid

The 1,5-benzoxazepinedione 1 is obtained from 2-aminophenol and the 5,5 -diphenyl ester of dithiomalonic acid in the presence of a catalytic amount of 4-(dimethylamino)pyridine.37... [Pg.316]

In the presence of a tertiary amine, particularly DABCO, S,S -diethyl dithiomalon-ate undergoes 1,4-addition to 2,/ -enones and a,/ -unsaturated esters that are not disubstituted in the /(-position. The products are reduced by acid-washed Raney nickel to 1,5-ketols and 5-hydroxy esters.2... [Pg.82]

Various routes to OO-diethyl dithiomalonate (202a) have been described, together with methods for its conversion into the analogous dithioester (202b) and bis-dithioester (202c). A simple procedure has been developed for the synthesis of unsymmetrical bis-acyl disulphides (203) from two thiobenzoic acids. ... [Pg.137]
