-
1,2-Cyclododecandione(4) was synthesized from dodecanedioic acid via esterification,acyloin condensation,oxidation in an overall yield of 43.1%.Reaction of dodecanedioic acid with methanol gave dodecanedioic acid dimethyl ester(2) with a yield of 86.5%.Compound 3 was obtained from compound 2 through acyloin condensation and the yield reached up to 63.1%,which was oxidized to compound 4 by bromine water as the oxidation reagent with a yield of 79%.The target compound was a light yellow crystal and was characterized by means of IR,1H NMR and 13C NMR.
