Synthesis of Hindered α-Amino Carbonyls: Copper-Catalyzed Radical Addition with Nitroso Compounds

The synthesis of sterically hindered anilines has been a significant challenge in organic chemistry. Here we report a Cu-catalyzed radical addition with in situ-generated nitroso compounds to prepare sterically hindered amines directly from readily available materials. The transformation is conducted at room temperature, uses abundant copper salts, and is tolerant of a range of functional groups.

Synthesis of 4-anilinopiperidine methyl esters, intermediates in the production of carfentanil, sufentanil, and remifentanil

Two spirodiaza intermediates have been made and employed in the synthesis of 4-anilinopiperidine methyl esters. These intermediates can be utilized in the production of commercial synthetic analgesics carfentanil, sufentanil, and remifentanil.

Syntheses, biological evaluation, and molecular modeling of 18F-labeled 4-anilidopiperidines as μ-opioid receptor imaging agents

The synthesis, evaluation, and molecular modeling of a series of 18F-labeled 4-anilidopiperidines with high affinities for the μ-opioid receptor (μ-OR) are reported. On the basis of the high brain uptake and selective retention in brain regions that contain a high concentration of the μ-OR, combined with a good metabolic stability, [ 18F]fluoro-pentyl carfentanil ([18F]4) and 2-(±)[18F]-fluoropropyl-sufentanil ([18F]6) were selected as the lead compounds for further evaluation. The binding affinity to the human μ-OR was 0.74 and 0.13 nM for [18F]4 and [ 18F]6, respectively. In vitro autoradiography of [18F] 4 and [18F] 6 on rat brain sections produced patterns in accordance with the known distribution of μ-OR expression. Structure-activity relationships of the fluorinated compounds are discussed with respect to the interaction with an activated-state model of the μ-OR. Taken together, the in vivo and in vitro data indicate that [18F] 4 and [18F] 6 hold promise for studying the μ-opioid receptor in humans by means of positron emission tomography.

The conversion of amides to esters with Meerwein's reagent. Application to the synthesis of a carfentanil precursor

An efficient two step transformation of 1°and 2°amides to methyl and ethyl esters has been developed using trimethyl- and triethyloxonium tetrafluoroborates, and dilute acid. This methodology was applied to 1-benzyl-4-phenylamino-4-piperidinecarboxamide, a precursor in the synthesis of carfentanil, to produce the methyl ester in 60% yield and the ethyl ester in 80% yield.
