Orthogonally Reacting Boron Coupling Reagents: A Novel Multicomponent-Multicatalytic Reaction [(MC)2R] of Dichlorovinylpyrazine

The results presented herein illustrate the feasibility of two orthogonally reacting boron coupling reagents as a new control strategy in multicomponent-multicatalytic reaction [(MC)2R] chemistry. A process employing dichlorovinylpyrazine merging the rhodium-catalyzed hydroarylation with the Suzuki coupling has been discovered. Three new bonds are formed in a one-pot, one-step process efficiently providing highly substituted diaza-dihydrodibenzoxepine products.

PRODUCTION AND USE OF ZINC AMIDES

The application relates to a reagent of the general formula [in-line-formulae]R1R2N—ZnY LiY??(I)[/in-line-formulae] wherein R1, R2 are, independently, selected from H, substituted or unsubstituted aryl or heteroaryl containing one or more heteroatoms, linear, branched or cyclic, substituted or unsubstituted alkyl, alkenyl, alkynyl, or silyl derivatives thereof; and R1 and R2 together can be part of a cyclic or polymeric structure; and wherein at least one of R1 and R2 is other than H; Y is selected from the group consisting of F; Cl; Br; I; CN; SCN; NCO; Halon, wherein n=3 or 4 and Hal is selected from Cl, Br and I; NO3; BF4; PF6; H; a carboxylate of the general formula RXCO2; an alcoholate of the general formula ORX; a thiolate of the general formula SRX; RXP(O)O2; or SCORX; or SCSRX; OnSRx; wherein n=2 or 3; or NOn, wherein n=2 or 3; and a derivative thereof; wherein Rx is a substituted or unsubstituted aryl or heteroaryl containing one or more heteroatoms, linear, branched or cyclic, substituted or unsubstituted alkyl, alkenyl, alkynyl, or derivatives thereof, or H; or as adduct with a solvent; as well as to the preparation and use thereof. 34

Regio-and chemoselective zincation of sensitive and moderately activated aromatics and heteroaromatics using TMPZnCl·LiCl

(Figure Presented) A broad range of functionalized aryl- and heteroarylzinc reagents were prepared via directed zincation of sensitive and moderately activated aromatics and heteroaromatics using TMPZnCl·LiCl under various reaction conditions. Diverse sensitive functional groups such as a nitro group, an aldehyde, an ester, and a nitrile are readily tolerated and are compatible with high metalation temperatures. Furthermore, the resulting zinc organometallics display an excellent reactivity toward various classes of electrophiles providing functionalized aromatics and heteroaromatics in high yields.
