Click inspired novel pyrazole-triazole-persulfonimide & pyrazole-triazole-aryl derivatives; Design, synthesis, DPP-4 inhibitor with potential anti-diabetic agents

This work presented the first report on designing, synthesizing of novel pyrazole-triazole-persulfonimide (7a-i) and pyrazole-triazole-aryl derivatives (8a-j) via click reaction using CuI catalyst and evaluated for their anti-diabetic activity and DPP-4 i

Fluorocyclization of Allyl Alcohols and Amines to Access 3-Functionalized Oxetanes and Azetidines

An efficient method to prepare 3-functionalized oxetanes and azetidines has been realized by fluorocyclization of readily available 2-azidoallyl/2-alkoxyallyl alcohols and amines. Notably, this is the first example applying the fluorocyclization strategy to construct four-membered heterocycles. The pendant electron-donating group (-N3 or -OR) plays a crucial role in polarizing the C= C double bond and facilitating the cyclization process, as verified by DFT and experimental studies.

Ruthenium Carbene-Mediated Construction of Strained Allenes via the Enyne Cross-Metathesis/Cyclopropanation of 1,6-Enynes

Herein, we report on the unprecedented dimerization of 1,6-enynes using a commercially available ruthenium complex RuCl2(PPh3)3, which results in a series of bicyclo[3.1.0]hexyl allene derivatives in moderate to excellent yields. Mechanistic investigation indicates that the in-situ-generated ruthenium vinylidene undergoes a site-selective metathesis process to provide allenyl ruthenium carbene, which can be intramolecularly trapped by the pendent C=C bond of enyne through a [2 + 2] cycloaddition/metal elimination process.

Orthogonal Syntheses of 3.2.0 Bicycles from Enallenes Promoted by Visible Light

P-TsOH Promoted Au(I)-Catalyzed Consecutive Endo Cyclization of Yne-Tethered Ynamide: Access to Benzofused Dihydroisoquinolones

A novel synthetic route to benzo[f]dihydroisoquinolone through a p-TsOH promoted cascade cyclization of easily accessible diyne-tethered ynamides in the presence of a Au(I)-catalyst is described. This reaction unveils a broad substrate scope, constructing a wide range of benzo[f]dihydroisoquinolones in good yields. The diyne-tethered ynamides are synthesized from inexpensive o-iodoaniline through Sonogashira couplings and the Cu-mediated C-N bond formation. The role of p-TsOH is examined, and the reaction pathway is also deduced. The benzo[f]isoquinoline scaffold is constructed from benzo[f]dihydroisoquinolones.
