Me3SiCl-promoted three-component coupling reaction of a functionalized enamine, an acetal, and an alkyne: an unprecedented approach to the synthesis of tetrasubstituted pyridines via a [3 + 2 + 1] intermolecular cyclization.

Toshiaki Sasada et al.

The Journal of organic chemistry, 73(17), 6905-6908 (2008-07-30)

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.

Simultaneous determination of cocaine and benzoyl ecgonine in urine by gas chromatography with on-column alkylation.

N C Jain et al.

Journal of forensic sciences, 22(1), 7-16 (1977-01-01)

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
