  Intramolecular Cycloaddition of Isomunchnone Dipoles to Heteroaromatic .pi.-Systems

  摘要：

  A series of furanyl-, thienyl-, and indole-substituted diazo imides were prepared by treating the appropriate amides with diketene to give the N-acetoacylated imides. Exposure of the imides to standard diazo transfer conditions afforded the desired diazo imides. Treatment of these diazo imides bearing tethered heterocyclic rings with rhodium(II) acetate affords transient isomunchnone dipoles. The mesoionic dipoles are formed by cyclization of the rhodium carbenoid onto the neighboring amide carbonyl oxygen atom. The scope and limitations of the intramolecular 1,3-dipolar cycloaddition of the isomunchnones across a tethered furan and thiophene ring were studied. The facility of the internal cycloaddition is influenced by the length and nature of the tether connecting the dipole and dipolarophile functionalities. The reaction is critically dependent on conformational factors in the transition state. In addition, the first examples of intramolecular cycloaddition of isomunchnones to indole dipolarophiles are reported. Cycloadditions of this type generate highly functionalized polyheterocyclic systems with complete relative stereocontrol at the newly formed stereocenters.

  azides can be effectively activated by the cobalt(II) complexes of D2-symmetric chiral amidoporphyrins for enantioselective radical 1,5-C-H amination to stereoselectively construct 5-membered cyclic sulfonamides. In addition to C-H bonds with varied electronic properties, the Co(II)-based metalloradical system features chemoselective amination of allylic C-H bonds and is compatible with heteroaryl groups

  The first cobalt-catalyzed asymmetric Kumada cross-coupling with high enantioselectivity has been developed. The reaction affords a unique strategy for the enantioselective arylation of α-bromo esters catalyzed by a cobalt-bisoxazoline complex. A variety of chiral α-arylalkanoic esters were prepared in excellent enantioselectivity and yield (up to 97% ee and 96% yield). The arylated products were transformed

  The terminal‐selective, remote C(sp3)−H alkylation of alkenes was achieved by a relay process combining NiH‐catalyzed hydrometalation, chain walking, and alkylation. This method enables the construction of unfunctionalized C(sp3)−C(sp3) bonds under mild conditions from two simple feedstock chemicals, namely olefins and alkyl halides. The practical value of this transformation is further demonstrated

  烯烃的末端选择性远程C（sp 3）-H烷基化是通过结合NiH催化的加氢金属化，链行走和烷基化的中继过程实现的。该方法能够在温和条件下由两种简单的原料化学品即烯烃和烷基卤化物构造未官能化的C（sp 3）-C（sp 3）键。在低催化剂负载下，烯烃异构混合物的大规模和区域会聚烷基化进一步证明了这种转化的实用价值。

  Copper complexes generated in situ from CuCl2, alkyl Grignard reagents, and 1,3‐dienes play important roles as catalytic active species for the 1,2‐hydroalkylation of 1,3‐dienes by alkyl fluorides through CF bond cleavage. The alkyl group is introduced to an internal carbon atom of the 1,3‐diene regioselectively, thus giving rise to the branched terminal alkene product.
