α-Arylation of Saturated Azacycles and N-Methylamines via Palladium(II)-Catalyzed C(sp3)-H Coupling

Pd(II)-catalyzed α-C(sp3)-H arylation of pyrrolidines, piperidines, azepanes, and N-methylamines with arylboronic acids has been developed for the first time. This transformation is applicable to wide arrays of pyrrolidines and boronic acids, including heteroaromatic boronic acids. A diastereoselective one-pot heterodiarylation of pyrrolidines has also been achieved.

Dichlorothiophosphoric acid and dichlorothiophosphate anion as thionating agents in the synthesis of thioamides

A method for the thionation of carboxylic acid amides with dichlorothiophosphoric acid and dichlorothiophosphate anion, providing thioamides in high yields, was developed. The facility of the thionation and the yields of the final products were shown to depend on the nature of the starting amide. The optimal reaction conditions are reported.

THIONO COMPOUNDS. 7. OXIDATION OF THIOAMIDES IN RELATION TO ADVERSE BIOLOGICAL EFFECTS

Thioacetamide, thioacetamide S-oxide (1), and thiopivalamide S-oxide (8) were oxidized with H2O2 in H2(18)O to generate the corresponding amides with at least 50percent 18O incorporation; hydrolysis of the S-oxides to the amides or 18O exchange with the amides occurs much more slowly.When 1 and trifluorothioacetamide (6) were oxidized with three and four equivalents of H2O2, respectively, in the presence of benzylamine, N-acetylbenzylamine (5) and N-benzyltrifluoroacetamide (7) were isolated in respective yields of 17percent and 37percent.These results are interpreted as evidence for an oxidative desulfurization mechanism involving nucleophilic attack at the carbon atom of an S,S-dioxide or trioxide intermediate as the major pathway; a minor pathway may involve the intermediacy of an oxathiirane S-oxide (3) or dioxide (4) species.Understanding is added to the behavior of S-oxides in aqueous solution, as well as to thermal stability in deuterochloroform.Also reported are studies of the preparation and properties of some N,N-dialkyl derivatives of 8, of reduction of 1 with NADH or NADPH, and of generation and trapping of species related to sulfoxylate ion.
