Zinc-catalyzed transamidation and esterification of N-benzoyl cytosine via C–N bond cleavage

Abstract

We have utilized N-benzoyl cytosine for efficient transamidation and esterification via catalytic C–N bond cleavage. The one-pot strategy involves the reaction of secondary amide with various aliphatic or aromatic amines...

Synthesis of Alkynylsilanes: A Review of the State of the Art

“…opting for the convenience of commercially available and easily manageable zinc triflate. It is worth noting that zinc triflate, a type of salt akin to other d-block metal triflates, finds widespread utility in both organic [46][47][48] and organosilicon synthesis. [49,50] The experiments yielded eight 1-alkynylsilanes, with 6 featuring a trimethylsilyl group.…”

Preparation and Characterization of Zinc(II)-Based Lewis/Brønsted Acidic Deep Eutectic Solvents

“…Zinc(II) is acidic in nature, as the 4s and 4p orbitals are empty and available for coordination [1], whereas the 3d orbitals are full and, unlike many other late transition metals, redox-stable. This makes zinc(II) salts good catalysts for many reactions [2]: among others, we can remember the Friedel-Craft benzylation of benzenes [3], the Biginelli reaction [4], alkyne hydrogenation to alkenes [5], activation of CO 2 [6], trans-amidation [7], and trans-esterification [8]. The latter has been also extended to polyester synthesis and degradation [9][10][11].…”

Transamidation of secondary carboxamides and amidation of esters are facilitated by magnetic Co@NC nanoparticles, as a highly efficient and recyclable catalyst under neat conditions

“…Additionally, amides serve as crucial intermediates and precursors in the realm of organic synthesis. 4–6 The presence of carboxamide functional groups within diverse compounds facilitates the prevention and treatment of numerous health disorders. 7–9 Some drugs are shown in Fig.…”
