Iodine has been recognized as an efficient, non-toxic, readily available and easy-to-handle
electrophilic reagent to favour halocyclization reactions for the synthesis of novel …

Carbo-and heterocycles frequently serve as crucial scaffolds in drugs, natural products, fine
chemicals, and biologically and pharmaceutically active compounds. Consequently, the …

A new method for the AgSCF3-mediated radical cascade difunctionalizing
trifluoromethythiolation of alkynes with dearomatization is developed. This protocol provides …

Metal carbene is an active synthetic intermediate, which has shown versatile applications in
synthetic chemistry. Although a variety of catalytic methods have been disclosed for the …

The fluoride-assisted ethynylation of ketones and aldehydes is described using
commercially available calcium carbide with typically 5 mol% of TBAF· 3H2O as the catalyst …

An ammonium acetate assisted gold-catalyzed cascade cyclization reaction of 2-
alkynylarylketones is described. Under the reported conditions, a gold-catalyzed …

Iodocyclization of propargyl alcohols is an active area for the construction of
hetero/carbocyclic iodides. Ambiphilic reactivity of propargyl alcohols made it more attractive …

We present a facile switchable regioselective 7-endo or 6-exo iodocyclization of O-homoallyl
benzimidates here, which affords various iodo-substituted 1, 3-oxazines and tetrahydro-1, 3 …

Two efficient processes based on the iodocyclization of ynamides have been developed:(i)
N-alkynyl tert-butyloxycarbamates were found to undergo a rare 6-exo-dig ring closure …

An iodine promoted cascade cycloisomerization of 1-en-6, 11-diynes is presented for the
easy preparation of tetrahydrobenzo [f] isoquinolines. This developed reaction system is …
