<sup>1</sup>-Alkylation of Dihydrolysergic Acid

日期:——
A new procedure for alkylating dihydrolysergic acid (1) on the indole nitrogen is reported. Previous procedures involved reaction of the indoyl anion with an alkyl halide. As the alkyl group gets larger, dehydrohalogenation of the alkyl halide becomes the preferred reaction and little or no N 1-alkylation occurs. By using alkyl tosylates in place of alkyl halides, we have been able to alkylate 1 on the indole nitrogen with a wide variety of alkyl groups in high yield.

Provided are compounds having an inhibitory effect on sodium-dependent glucose cotransporter SGLT. The invention also provides pharmaceutical compositions, methods of preparing the compounds, synthetic intermediates, and methods of using the compounds, independently or in combination with other therapeutic agents, for treating diseases and conditions which are affected by SGLT inhibition.
Alkenes, arenes, and heteroarenes possessing an 8-quinolylamide group as the directing group are alkylated with primary and secondary alkyl tosylates, mesylate, and halides in the presence of Fe(acac)3/diphosphine as a catalyst and ArZnBr as a base. The reaction proceeds stereospecifically for alkene substrates and takes place without loss of regiochemical integrity of the starting secondary tosylate

The C(sp3)–C(sp3) cross-coupling of alkyl halides with alkyl tosylates has been developed by employing a combination of nickel and nucleophilic cobalt catalysts in the presence of a manganese reductant. This method provides a straightforward route to a diverse set of not only secondary–primary but also primary–primary C(sp3)–C(sp3) linkages under mild conditions without using alkyl-metallic reagents
