  Highly Regioselective Carbonylation of Unactivated C(sp³)–H Bonds by Ruthenium Carbonyl

  摘要：

  The regioselective carbonylation of unactivated C(sp(3))-H bonds of aliphatic amides was achieved using Ru-3(CO)(12) as a catalyst. The presence of a 2-pyridinylmethylamine moiety in the amide is crucial for a successful reaction. The reaction shows a preference for C-H bonds of methyl groups as opposed to methylene C-H bonds and tolerates a variety of functional groups. The stoichiometric reaction of an amide with Ru-3(CO)(12) gave a dinuclear ruthenium complex in which the 2-pyridinylmethylamino moiety was coordinated to the ruthenium center in an N,N manner.

  foximine (MPyS) directed bromination and chlorination of the 1°-β-C(sp3)–H bond of MPyS-N-amides is realized under the influence of N-Br/Cl-phthalimides and a Pd(II)-catalyst. The sequential halogenation and acetoxylation of α-dimethyl MPyS-N-amides constructs highly functionalized α-trisubstituted aliphatic acid derivatives. The MPyS directing group is cleaved from the halogenated products and recovered

  unactivated C(sp3)−H bonds by cyclic alkylamines mediated by Cu(OAc)2/O2 is reported. This method avoids the use of benzoyloxyamines as the aminating reagent, which are normally prepared from alkylamines in extra steps. A variety of unnatural β2, 2‐amino acid analogues are synthesized by this simple and efficient procedure. This approach offers a solution to the previous unmet challenge of C(sp3)−H/N−H

  palladium‐catalyzed C(sp3)−H activation that enables the direct alkynylation of free carboxylic acid substrates. In contrast to previous synthetic methods, no introduction/removal of an exogenous directing group is required. A broad scope of acids including both α‐quaternary and challenging α‐non‐quaternary can be used as substrates. Additionally, the alkynylation in the distal γ‐position is reported. Finally
