General description

2,2,2-Trichloroethyl chloroformate (TrocCl) serves as a versatile reagent used for selective acylation and dealkylation in organic synthesis. It is used in regio, chemo, and stereoselective synthesis.

Application

  • 2,2,2-Trichloroethyl chloroformate was used as derivatizing reagent in gas chromatographic/mass spectrometric determination of a large range of amphetamine-related drugs and ephedrines in plasma, urine and hair samples.
  • It was used as starting reagent during the synthesis of 6-Nor-9,10-dihydrolysergic acid methyl ester.
  • It was used as reagent during N-demethylation of dextromethorphan.
  • It was used as protecting reagent for aliphatic and aromatic hydroxyl and amino groups.
Protecting reagent for aliphatic and aromatic hydroxyl and amino groups.

6-Nor-9,10-dihydrolysergic acid methyl ester (IV) was prepared by demethylation of 9,10-dihydrolysergic acid methyl ester (II) with 2,2,2-trichloroethyl chloroformate, followed by reduction of the intermediate carbamate (III) with zinc in acetic acid. The 6-ethyl-V and 6-n-propyl-VI derivatives were prepared by alkylation

Amphetamine and methamphetamine are commonly abused central nervous system stimulants. We describe a rapid new derivatization of amphetamine and methamphetamine using 2,2,2-trichloroethyl chloroformate for gas chromatography-mass spectrometric analysis. Amphetamine and methamphetamine, along with N-propyl amphetamine (internal standard), were extracted from
2, 2, 2-Trichloroethyl Chloroformate (TrocCl)
