  带有咪唑环的芳香酰胺的构象性质和酸诱导的反式-顺式酰胺转换

  摘要：

  带有仲酰胺键的芳香酰胺在晶体和溶液中均以反式构象存在，而N-甲基化衍生物的构象在晶体中为顺式，在各种溶剂中以顺式构象为主。 N-烷基化苯甲酰苯胺的顺式构象偏好提供了获得芳香族折叠体的途径，例如采用动态螺旋结构的低聚( N-烷基-对苯甲酰胺)。在此，检查了晶体和溶液中咪唑取代酰胺的构象性质。咪唑取代酰胺2a和4a在溶液中主要以顺式构象存在。 N-甲基-N- (1-甲基-1H-咪唑-4-基)苯甲酰胺( 4a )的顺式构象异构体比例小于N ,1-二甲基-N-苯基-1H-咪唑-2-甲酰胺( 2a )或N-甲基苯甲酰苯胺，但取代基的引入强烈影响构象异构体比率。咪唑环上带有吸电子基团的化合物6a和7a主要以反式形式存在。另一方面，在苯环上引入吸电子基团或在4a的酰胺氮上引入大体积取代基增加了顺式构象异构体的比例。此外，通过添加酸， N-烷基化的N-咪唑酰胺的主要构象异构体从顺式转变为反式。这些结果表明

  Phenylcarbamoylation of N-Acetyl-1,2,4-triazolium-4-aminides Revisited

  摘要：

  The reaction of N-acetyl-1,2,4-triazolium-4-aminides (I, i.e. 1Aa-d) with phenyl isocyanate affords ring functionalized products (4a-d) rather than linear adducts (II). Analogous compounds are obtained from the triazolium-1-aminide (1Ae) and the imidazolium congener (W). Twofold carbamoylation to give products of type (8) occurs on reaction of aminotriazolium salts (7A) in the presence of base. Azoliums having methyl at C(5)/(2) are inert throughout (B series).

• Iridium-Catalyzed Direct Amidation of Imidazoles at the C-2 Position with Isocyanates in the Presence of Hydrosilanes Leading to Imidazole-2-Carboxamides

  Regioselective coupling reaction of N-substituted imidazoles with isocyanates in the presence of a stoichiometric amount of hydrosilanes catalyzed by Ir4(CO)12 to give imidazole-2-carboxamides is reported. Imidazoles bearing an (O-silyl)carboximidate group at the 2-position appear to be initially formed in the reaction; these are then hydrolyzed to the final products in situ. The addition of the hydrosilane

• Di-<i>tert</i>-butyl Dicarbonate and 4-(Dimethylamino)pyridine Revisited. Their Reactions with Amines and Alcohols¹

  The reaction of BOC2O in the presence and absence of DMAP was examined with some amines, alcohols, diols, amino alcohols, and aminothiols. Often, unusual products were observed depending on the ratio of reagents, reaction time, polarity of solvent, pK(a) of alcohols, or type of amine (primary or secondary). In reactions of aliphatic alcohols with BOC2O/DMAP, we isolated for the first time carbonic-carbonic anhydride intermediates; this helps explain the formation of symmetrical carbonates in addition to the O-BOC products. In the case of secondary amines, we succeeded to isolate unstable carbamic-carbonic anhydride intermediates that in the presence of DMAP led to the final N-BOC product. The effect of N-methylimidazole in place of DMAP was also examined.
• α-Nitrogen activating effect in the room temperature copper-promoted N-arylation of heteroarylcarboxamides with phenyl siloxane or p-toluylboronic acid

  Heteroarylcarboxamides containing a-nitrogens undergo copper-promoted N-phenylation with hypervalent phenyl trimethylsiloxane at room temperature, in the absence of base and in air. Arylboronic acid can substitute for phenyl trimethylsiloxane as the organometalloid. The ol-heteroatom chelating effect is in the decreasing order of N>O, S. This discovery opens up the possibility of using other alpha -nitrogen functional groups to direct the N-arylation of peptides and simple amides under conditions as mild as that of amide bond formation.
