Synthesis of Isoquinolylselenocyanates and Quinolylselenocyanates via Electrophilic Selenocyanogen Cyclization Induced by Pseudohalogen (SeCN)2 Generated in situ

Jia Wang et al.

Summary: A strategy for the synthesis of isoquinolylselenocyanates and quinolylselenocyanates through electrophilic selenocyanogen cyclization has been developed, with the sequential process induced directly by generated in situ pseudohalogen (SeCN)2. The obtained selenocyanates allowed functional group diversification, potentially serving as valuable intermediates for compounds.

NaN(SiMe3)2/CsTFA Copromoted Aminobenzylation/Cyclization of 2-Isocyanobenzaldehydes with Toluene Derivatives or Benzyl Compounds: One-Pot Access to Dihydroquinazolines and Quinazolines

Xiang-He Meng et al.

Summary: A NaN(SiMe3)(2)/CsTFA copromoted aminobenzylation/cyclization reaction of 2-isocyanobenzaldehydes with toluene derivatives or benzyl compounds has been developed, providing a simple and efficient strategy for the synthesis of 4-benzyl-substitued dihydroquinazoline and quinazoline derivatives from easily available acyclic starting materials in a single step. Further applications demonstrated the tremendous potential of the tandem reaction in the synthesis of quinazoline, dihydroindolo[1,2-c]quinazoline, and dihydro-8H-isoquinolino[2,3-c]quinazoline.

Rhodium-catalyzed coupling-cyclization reaction of isocyanides and 2-azidophenyloxyacrylates: synthesis of N-(3-substituted benzo[d]oxazol-2(3H)-ylidene)amines and dihydrobenzo[d]oxazoles

Ming Yang et al.

Summary: A rhodium-catalyzed coupling cyclization has been developed for the first time with isocyanides and 2-azidophenyloxyacrylates. This reaction allows for the divergent syntheses of two significant N-heterocycles in a single step from readily available starting materials.

Synthesis of novel benzo naphtho naphthyridines from 2,4-dicloroquinolines

Prabha Kolandaivel et al.

Summary: A schematic study on the condensation of 2,4-dichloroquinolines with 1-naphthyamine in the presence of CuI as a catalyst was conducted, resulting in the functionalized mono and di-substituted naphthylamino quinolines. Additionally, the synthesis of linear and angular benzo[b]naphtho[2,1-g][1,8]naphthyridines was achieved through cyclization reactions catalyzed by polyphosphoric acid, with good yields. Further synthesis of benzo[g]naphtho [2,1-b][1,8]naphthyridines and benzo[h]naphtho[2,1-g][1,8]naphthyridines from 2,4-dichlorobenzo[h]quinoline with various anilines was also described.

Palladium-Catalyzed One-Pot Synthesis of Pyrroloindolines from 2-Alkynyl Arylazides and Thioacetamides

Ping Li et al.

Summary: A novel and efficient synthetic method was developed for the preparation of various pyrroloindolines from 2-alkynyl arylazides and thioacetamides. The reaction was carried out in a one-pot process under mild reaction conditions to afford the products in moderate to good yields, showing potential for use in organic synthesis.
