γ-Selective Allylation of (E)-Alkenylzinc Iodides Prepared by Reductive Coupling of Arylacetylenes with Alkyl Iodides.
The first examples of Cu-catalyzed γ-selective allylic alkenylation using organozinc reagents are reported. (E)-Alkenylzinc iodides were prepared by Fe-catalyzed reductive coupling of terminal arylalkynes with alkyl iodides. In the presence of a copper catalyst, these reagents reacted with allylic bromides derived from Morita-Baylis-Hillman alcohols to give 1,4-dienes in high yields. The reacti...
متن کاملDecarboxylative Cross-Electrophile Coupling of N-Hydroxyphthalimide Esters with Aryl Iodides
A new method for the decarboxylative coupling of alkyl N-hydroxyphthalimide esters (NHP esters) with aryl iodides is presented. In contrast to previous studies that form alkyl radicals from carboxylic acid derivatives, no photocatalyst, light, or arylmetal reagent is needed, only nickel and a reducing agent (Zn). Methyl, primary, and secondary alkyl groups can all be coupled in good yield (77% ...
متن کاملRegioselective zincation of indazoles using TMP2Zn and Negishi cross-coupling with aryl and heteroaryl iodides.
The metalation of various SEM-protected functionalized indazoles with TMP(2)Zn provides 3-zincated indazoles which undergo palladium-catalyzed Negishi cross-couplings in good yields.
متن کاملEfficient copper-catalyzed coupling of aryl chlorides, bromides and iodides with aqueous ammonia.
The copper(I)-catalyzed synthesis of a range of primary anilines from electron-rich and electron-deficient aryl halides including aryl chlorides has been achieved with aqueous ammonia, avoiding the need for inert atmosphere, expensive catalysts and ligands, anhydrous solvents, and additional base or other additives.
متن کاملPalladium-catalyzed asymmetric coupling cyclization of terminal γ-allenols with aryl iodides.
A Pd-catalyzed asymmetric coupling cyclization of γ-allenols has been developed. Styrenyl derivatives can be prepared in 60-86% yields with ee values ranging from 85-92%.
