Fatty acid amide hydrolase (FAAH) regulates a large class of signaling lipids, including the endocannabinoid anandamide. Carbamate inhibitors of FAAH display analgesic and anxiolytic properties in rodents. However, the mechanism by which carbamates inhibit FAAH remains obscure. Here, we provide biochemical evidence that carbamates covalently modify the active site of FAAH by adopting an orienta...

The use of carbamates has been implicated in several suicides and in accidental poisoning. Rapid identification of these carbamates in clinical samples can direct the course of medical intervation and help save lives. In this study, we describe a new, operationally simple, and rapid method that employs a gas chromatograph (GC) or gas chromatograph-mass spectrometer (GC-MS) coupled to a NeedlEx®...

A series of α-alkoxy carbamates that cleave under mild conditions to release alcohols has been synthesized through a multicomponent process. The relationship between structural features in these compounds and the rate of alcohol release in the presence of basic hydrogen peroxide has been studied. The preparation of carbamates that cleave under other conditions has been demonstrated.

The objective of this article is to describe allergic contact dermatitis from sodium isopropyl xanthate, potassium amyl xanthate, and carbamates in a geotechnician, to discuss possible cross-reactions, and to report the widespread use of carbamates and mercaptobenzothiazole in mining processes.

It is shown from the kinetics of inhibition of cholinesterase by N-methylcarbamates and organo-phosphates that the LD50 dose is likely to be a much greater multiple of the dose causing signs of poisoning in 50%-of the animals (the ED50) for the carbamates than for the organophosphates. The expected difference was demonstrated by a comparison of the LD50s and ED50s, intravenous and intramuscular...

The rhodium(III)-catalyzed mild and site-selective C-H allylation of enol carbamates with 4-vinyl-1,3-dioxolan-2-one and allylic carbonates affords allylic alcohols and terminal allylated products, respectively. The assistance of the carbamoyl directing group provides a straightforward preparation of biologically and synthetically important allylated enol carbamates.

In the 40 years since the inception of dynamic NMR methods, much effort has been invested to quantify and understand the barrier to rotation about the C-N bond in amides.1 Carbamates, which also exhibit the approximately planar N-CdO framework responsible for hindered rotation in amides, have received considerably less attention, although they are important biologically as anticonvulsants, loca...

A one-pot synthesis of new variously substituted γ-chloro-γ, β-allylic carbamates have been carried out starting from β-chloro-α, β-unsaturated aldehydes. The and the corresponding intermediates, alcohols, were fully characterized by (1H 13C) NMR, IR HRMS spectroscopic techniques. crystal structures two allylic carbamates, established single-crystal X-ray diffraction.

The enantioselective domino reaction between CO2 (1 atm), amines and linear allyl chlorides in the presence of an iridium complex, DABCO and toluene at 15 °C was realized, which gave branched allyl carbamates in acceptable to high yields with up to excellent regioselectivity (99/1) and 94% ee. This is the first example of the synthesis of chiral allyl carbamates through catalytic domino reactio...
