Microwave-assisted organic synthesis (MAOS) has emerged as a transformative technique in organic chemistry, significantly enhancing the speed, efficiency, and selectivity of chemical reactions. In our research, we have employed microwave irradiation to expedite the synthesis of quinazolinones, using water as an eco-friendly solvent and thereby adhering to the principles of green chemistry. Notably, the purification

Highly valued products resulting from reductive aminations utilizing shelf-stable bisulfiteadditioncompounds of aldehydes can be made under aqueous micellar catalysis conditions. Readily available α-picolineborane serves as the stoichiometric hydride source. Recycling of the aqueous reaction medium is easily accomplished, and several applications to targets in the pharmaceutical industry are documented

with solid reagents. We have showcased the practicality of Bertagnini's salts, also called aldehyde-bisulfite adducts, which are crystalline, simplifying preparation and storage. These salts are stable substitutes for liquid aldehydes and ketones that have been effectively employed in reductive amination, synthesizing aza-heterocycles and hydrazones within mechanochemistry. The technique's effectiveness
