“…Preliminary experiments with 10% phosphomolybdic acid gave products in rather good yields (75%, 2.5 h), but the use of indium salts as catalysts [62][63][64][65] (10 mol% In(OTf) 3 ) in acetonitrile at room temperature allowed the optimization of the synthesis of 3,4-dihydro-2H-benzo[b] [1,4] thiazine derivative (51a) up to 86% in terms of yields, with high diastereoselectivity and shorter reaction times (2 h) [61].…”

The Piancatelli Rearrangement: New Applications for an Intriguing Reaction

Nearly forty years ago, at the University of Rome, Giovanni Piancatelli and co-workers discovered the acid-catalyzed water-mediated rearrangement of 2-furylcarbinols into 4-hydroxycyclopentenones. These motifs are core components of several pharmacologically active compounds and precursors of many natural products. The main features of this reaction are the simple experimental conditions, the stereochemical outcome and the generality of the procedure. Consequently, a re-emergence of this reaction has been seen recently, including developments of the Piancatelli rearrangement with some interesting inter-and intramolecular variants. This review will mainly focus on the general aspects of the reaction along with its more recent applications.

“…Additionally, it is possible to modify the chemo‐, regio‐ and enantio‐selectivity of the catalyst. This reaction has been catalyzed by Cu, Au, Ag, Zn, Fe, Ni, Rh, Hg, In, Ir, Mn, Co, Bi, Cd . The homogenous catalysts do have some disadvantages, as they are difficult to separate from the reaction mixtures.…”

In the present study we have, synthesized silver nanoparticles supported on carbon nitride AgNPs@g‐C3N4 and investigated its catalytic aspects by using microwave. We found that silver nanoparticles supported on g‐C3N4 were highly active in the A3‐coupling reaction of (Aldehyde, secondary amine and terminal alkynes) for the synthesis of propargylamines with excellent yield up to 97% and in C−C coupling reaction of terminal alkynes for the synthesis of 1, 3‐diyne with excellent yield up to 98%. We have achieved excellent TON (72932), TOF (3636 min−1), E‐factor (0.27) and atom economy AE (94%). Reaction parameters like effect of catalyst quantity, effect of time and effect of temperature was deeply studied. The catalyst was characterized by SEM, HR‐TEM, EDX, XRD, ICP‐AES and IR.
