High-Throughput Synthesis of N3-Acylated Dihydropyrimidines Combining Microwave-Assisted Synthesis and Scavenging Techniques
摘要:
The solution-phase synthesis of N3-acylated dihydropyrimidines was achieved utilizing microwave flash heating both in the synthesis (acylation) and purification (scavenging) steps. Quenching times for excess anhydrides using polystyrene or silica-supported diamine sequestration reagents were reduced from several hours to minutes utilizing microwave irradiation. The use of water as sequestration agent, coupled with an efficient solid-phase extraction workup technique allowed the rapid generation of a 20-member library of N3-acylated dihydropyrimidines.

Rational Design, Synthesis, In Vitro, and In Silico Studies of Dihydropyrimidinone Derivatives as β-Glucuronidase Inhibitors
rationally designed as β-glucuronidaseinhibitors. These designed compounds were successfully synthesized and characterized through various spectroscopic techniques such as IR, 1H-NMR, 13C-NMR, and EI-MS. A structure-activity relationship (SAR) of synthesized derivatives to inhibitβ-glucuronidase was also established. In vitro biological evaluations revealed that 4i as the most potent compound in this series
