  N‐Fused heterocycles are of particular use and upmost importance in multiple fields. Herein, we disclose a conceptually new approach for the rapid assembly of N‐fused heteroarenes from alkenes. A portfolio of strategically designed heterocyclization reagents are readily prepared for the cascade reaction. A plethora of N‐fused heteroarenes including seven types of heterocyclic core are furnished. The

  The study of the Julia–Kocienski reaction between fluorinated arylsulfone and ketones is described. The corresponding fluoroalkenes were isolated in moderate to good yields from β- and δ-substituted cyclic ketones. From acyclic ketones and α-substituted cyclic ketones a decarbethoxylation reaction of the sulfonylesters occurred. This decarbethoxylation reaction opened a new route for the preparation

  Highly regioselective electrochemical fluorination of 2-pyrimidyl sulfides having an electron(EWG) withdrawing group at the position alpha to the sulfur atom was successfully carried out using Et4NF . nHF (n = 3, 4) or Et3N . 3HF as a supporting electrolyte and a fluoride ion source in 1,2-dimethoxyethane (DME) in an undivided cell. 2-Methylthiopyrimidine devoid of an EWG was also selectively fluorinated in DME to provide 2-(fluoromethylthio)pyrimidine in a moderate yield as 63%, while corresponding 2-methylthiopyridine was less selectively fluorinated in lower yield along with alpha,alpha-difluorinated product. In contrast, the corresponding 2-quinazolinonyl sulfides underwent similarly alpha-fluorination along with unexpected ipso-fluorination through anodic desulfurization.
