The first intermolecularPauson-Khandreaction conducted with internal alkynylboronic esters has been described. This strategy allows the installation of the boronic ester moiety in b-position of the cyclopentenone with total...
A simple and efficient strategy is proposed to significantly improve the antibacterialactivity of peptaibols and other antimicrobial peptides by N‐terminal capping with 1,2,3‐triazole bearing various hydrophobic substituents on C‐4. Such N‐terminal insertions on alamethicin F50/5 could enhance its antimicrobial activity on Gram‐positive bacteria without modification of its overall three‐dimensional

Silver nanoparticles supported on microcrystalline cellulose (Ag NPs@MCC), an active catalyst, has been discovered for the direct carbonylation of terminalalkynes with CO2 into carboxylicacid under mild and sustainable reaction conditions. The stabilized Ag NPs show higher distribution with a uniform particle size. The catalyst was characterized by PXRD, SEM, TEM, HR-TEM, EDS, EDX, ICP-AES and XPS
