Pd‐Catalyzed Cyclotrimerization and Cycloaddition of 5,6‐Didehydrobenzo[8]annulenes (BenzoCOTynes): Formation of Nonplanar Tri[8]annulenes and Diels–Alder Cycloadducts

European Journal of Organic Chemistry, EarlyView.
A Pd(0)‐catalyzed cyclotrimerization of benzoCOTynes to form tri(benzo[8]annulenes) was developed. Three distinct isomers were isolated and structurally characterized by single‐crystal X‐ray diffraction. Ligand modulation proved crucial for enhancing regioselectivity: P(4‐OMePh), and (S)‐tBu‐Phox promoted the formation of the symmetric isomers.

Synthesis of Novel C‐Acyl‐Glycosyl Sulfonamides via Pd‐Catalyzed Carbonylative Coupling

European Journal of Organic Chemistry, EarlyView.
A Pd‐catalyzed carbonylative coupling of 1‐iodo‐glycals with diverse sulfonamides using Mo(CO)6 enables efficient access to C‐acyl‐glycosyl sulfonamides.This robust and versatile strategy delivers novel glycoside derivatives in good to excellent yields, highlighting their potential for drug discovery.

By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

Environmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...
