A synthetic protocol for the preparation of α-acyl aminocarboxamides and α-amino amidines is proposed. The selectivity toward each of these two possible products was tuned by simple modifications of the reaction conditions. A broad scope is present

A transition metal-free protocol for the preparation of fluorescent and non-fluoresent 3-methylthio-4-arylmaleimides in a single step through a new rearrangement from thiazolidine-2,4-diones is described. By employing the optimized reaction condition

A selective hydrazine sensor in solution based on the 2,1,3-benzothiadiazole heterocycle is efficient for in vitro and in vivo analyses. This sensor generates water as the only byproduct, avoiding generation of toxic compounds and interference during

In this work, we describe the application of a synthetic enzyme (synzyme) as the catalyst to promote the multicomponent synthesis of isoxazol-5(4H)-one derivatives. The catalytic system could be used up to 15 times without any notable loss of its act

Herein, a combination of heteropolyacids and ionic liquids as a catalytic system was studied for the Biginelli multicomponent reaction; the positive ionic liquid effect associated with the acidic strength of zeolite-supported heteropolyacids made thi

This paper describes the synthesis of fluorescent peptoids using the Ugi multicomponent reaction (4CR). The four synthesized structures had their photophysical properties evaluated and their potential as biomarkers established. The peptidomimetics we
