Catalyst-Controlled Straightforward Synthesis of Highly Substituted Pyrroles/Furans via Propargylation/Cycloisomerization of α‑Oxoketene-N,S-acetals

Ganesh Chandra Nandi; Soumini, K (American Chemical Society, 2016-11-04)

A facile and efficient InCl3 catalyzed one-pot synthesis of highly substituted pyrroles has been developed via a tandem propargylation/cycloisomerization reaction of α- oxoketene-N,S-acetals with propargyl alcohols. ...
p‑TSA/Base-Promoted Propargylation/Cyclization of β‑Ketothioamides for the Regioselective Synthesis of Highly Substituted (Hydro)Thiophenes

Ganesh Chandra Nandi; Maya Shankar, Singh (ACS publication, 2016-06-21)

Metal-free, p-toluenesulfonic acid (p-TSA)- mediated, straightforward propargylation of β-ketothioamides with aryl propargyl alcohol has been achieved at room temperature. In addition, the reaction also provided ...
