• Electrochemical α-thiolation and azidation of 1,3-dicarbonyls

  DOI：10.1039/d1cc06891a

  日期：——

  A highly efficient electrochemical α-thiolation and azidation of 1,3-dicarbonyl compounds is developed. This electrochemical process is conducted under mild conditions without the use of a chemical oxidant, and exhibits a wide scope with good functional group tolerance. The applicability of this methodology was successfully demonstrated by modifying an anti-inflammatory drug on a gram scale.

  The radicals formed in Mn(III)-based oxidative free-radical cyclizations of beta-keto esters and malonate esters can be trapped with sodium azide and Mn(III) to give cyclic and bicyclic azides in 30-80% yield. Reduction of the azide gives bi- and tricyclic lactams. [reaction: see text]

• Radical Chain Reactions of α-Azido-β-keto Esters with Tributyltin Hydride. A Novel Entry to Amides and Lactams through Regiospecific Nitrogen Insertion

  A variety of acyclic and carbocyclic alpha-azido-beta-keto esters have been readily prepared from the parent dicarbonyl compounds, and their radical chain reactions with tributyltin hydride have been investigated. These reactions normally result in efficient production of alkoxycarbonyl-substituted amides and lactams and thence provide a new, useful method for regiospecific nitrogen insertion of keto ester compounds. The likely mechanism entails initial addition of tributylstannyl radical to the azido moiety to give a stannylaminyl radical, which readily undergoes intramolecular three-membered cyclization onto the ketone group to form an alkoxyl radical. The alkoxyl radical then undergoes regiospecific beta-scissian to form a stable ring-opened radical that is eventually reduced by tributyltin hydride to propagate the chain. With certain substrates, concomitant deazidation occurs to an important extent. This process, which is unusually observed in radical reactions of alkyl azides, is ascribed to addition of the stannyl radical to the terminal azido nitrogen; subsequent fragmentation of the ensuing 1,3-triazenyl adduct gives stannyl azide and a deazidated alkyl radical, resonance-stabilized by the adjacent carbonyl groups. The radical reactions of 2-azido-2-(ethoxy-carbonyl)-1-tetralone with allyltributylstannane and allyltriphenylstannane have also been investigated with the (missed) aim to achieve nitrogen insertion and concomitant allylation.
• Ring Transformation of α‐Amino‐β‐oxoesters to δ‐Butyrolactams

  日期：2023.10.16

  Lactams by Ring Transformation: δ-Butyrolactams with an exocyclic ester moiety in the δ-position were accessed by reduction of cyclic α-azido-β-oxocyclopentane carboxylates with Zn−AcOH. The ring transformation proceeded readily under the conditions of the reduction which is an unprecedented process.
