General description

N,N-Dimethylformamide diethyl acetal undergoes Me3SiCl-mediated three-component coupling reaction with alkyne to yield 2,3,4,5-tetrasubstituted pyridine derivatives.

Application

N,N-Dimethylformamide diethyl acetal was used in quantification of cocaine and its primary metabolite, benzoyl ecgonine from urine matrix by gas chromatography.

We have identified a Me3SiCl-mediated three-component coupling reaction of a functionalized enamine, N,N-dimethylformamide diethyl acetal, and an internal alkyne having an electron-withdrawing group that produces 2,3,4,5-tetrasubstituted pyridine derivatives in good to excellent yields via a single-step reaction.

A gas chromatographic procedure has been developed for the simultaneous determination of cocaine and benzoyl ecgonine in urine specimens. The two drugs are extracted by isopropanol/chloroform from urine samples saturated with a bisalt buffer. The organic extract is evaporated to
