The crystal structure of the title compound, C15H20N2orDippIm, is reported. At 106 (2) K, the molecule has monoclinicP21/c symmetry with four molecules in the unit cell. The imidazole ring is rotated 80.7 (1)° relative to the phenyl ring. Intermolecular stabilization primarily results from close contacts between the N atom at the 3-position on the imidazole ring and the C—H bond at the 4-position on the neighboringDippIm, with aryl–aryl distances outside of the accepted distance of 5 Å for π-stacking.

Purinyl N -directed aroylation of 6-arylpurine ribo- and 2′-deoxyribonucleosides, and mechanistic insights
The purinyl nitrogen atom is an effective metalation director, which in the presence of Pd(OAc)2,t-BuOOH, and aryl aldehydes, leads to acylation of the aryl ring at the C6 position of the purine.

Abstract Palladium‐catalyzed aryl amination and Heck arylation reactions are complementary transformations, generally requiring a suitable catalyst combination and a base. With substrates containing both an amino group and a vinyl moiety, control of C─N versus C─C reactivity can lead to regiodivergent functionalizations. With this focus, reactions of silyl‐protected 8‐vinyl 2'‐deoxyadenosine and adenosine with aryl bromides and iodides have been studied. Pd(OAc)2, Pd2(dba)3, and preformed dichloro[1,1′‐bis(di‐t‐butylphosphino)ferrocene]palladium (II) (Pd‐118) were evaluated as metal sources. Ligands tested were Xantphos, DPEphos, BIPHEP, and DPPF, with Cs2CO3and K3PO4as bases. In toluene as solvent, the Pd(OAc)2/Xantphos/Cs2CO3combination was uniquely capable of predominantN6arylation. Aryl bromides and iodides gave comparable product yields. Replacement of Cs2CO3with K3PO4redirected arylation from the nitrogen atom to the vinyl carbon atom, and all other catalyst, ligand, and base combinations gave Cvinylarylation as well. Simply switching from Pd(OAc)2to Pd2(dba)3resulted in loss of theN6‐selectivity and Cvinylarylation was favored. Based upon these results, using two structurally similar catalytic systems sequential CvinylandN6arylations of the nucleosides were accomplished. Some of the products were converted to other novel nucleoside analogues. Because some compounds were fluorescent, their photophysical properties were assessed experimentally and computationally.more » « less

Abstract Rh(I)‐catalyzed C8‐selective C−H alkenylation and arylation of 1,2,3,4‐tetrahydroquinolines with alkenyl and aryl carboxylic acids under microwave assistance have been realized. Using [Rh(CO)2(acac)] as the catalyst and Piv2O as the acid activator, 1,2,3,4‐tetrahydroquinolines undergo C8‐selective decarbonylative C−H alkenylation with a wide range of alkenyl and aryl carboxylic acids, affording the C8‐alkenylated or arylated 1,2,3,4‐tetrahydroquinolines. This method enables the synthesis of C8‐alkenylated 1,2,3,4‐tetrahydroquinolines that would otherwise be difficult to access by means of conventional C−H alkenylation protocols. Moreover, this catalytic system also works well in C8‐selective decarbonylative C−H arylation of 1,2,3,4‐tetrahydroquinolines with aryl carboxylic acids. The catalytic activity strongly depends on the choice of theN‐directing group, with the readily installable and removableN‐(2‐pyrimidyl) group being optimal. The catalytic pathway is elucidated by mechanistic experiments.more » « less

Abstract The synthesis of tris(ortho‐carboranyl)borane (BoCb3), a single site neutral Lewis superacid, in one pot from commercially available materials is achieved. The high fluoride ion affinity (FIA) confirms its classification as a Lewis superacid and the Gutmann‐Beckett method as well as adducts with Lewis bases indicate stronger Lewis acidity over the widely used fluorinated aryl boranes. The electron withdrawing effect ofortho‐carborane and lack of pi‐delocalization of the LUMO rationalize the unusually high Lewis acidity. Catalytic studies indicate that BoCb3is a superior catalyst for promoting C−F bond functionalization reactions than tris(pentafluorophenyl)borane [B(C6F5)3].more » « less

Abstract A variety of 1‐aryl‐1,3‐dienes were isomerized fromEtoZisomers by photocatalysis using Ru(bpy)3[PF6]2and blue LED light. Enrichment of theZ‐isomer is thought to occur by selective triplet energy transfer from the photocatalyst to the stereoisomeric mixture. The 1,3‐diene starting materials are easily made by catalytic ene‐yne metathesis (EYM). To access 1,3‐dieneZ‐stereoisomers directly, a one pot procedure was developed. Additional 1,3‐dienes were investigated for both isomerization andZ‐enrichment. The combination of cross EYM with photocatalysis allows for the stereoconvergent synthesis ofZ‐1,3‐dienes.more » « less
