Asymmetric Dearomatization of Phthalazines by Anion-Binding Catalysis. [PDF]
Org Lett, 2023 A straightforward methodology for the enantioselective synthesis of 1,2-dihydrophthalazines via dearomatization of phthalazines by anion-binding catalysis has been developed. The process involves the Mannich-type addition of silyl ketene acetals to in situ generated N-acylphthalazinium chlorides using a tert-leucine derived thiourea as a H-bond donor ...

Phthalazines and phthalazine hybrids as antimicrobial agents: Synthesis and biological evaluation [PDF]
Journal of Chemical Research, 2019 Phthalazine and phthalazinone derivatives are important owing to their significant biological activities and pharmacological properties. Herein, a benzoic acid derivative (2), a benzoxazin-1-one derivative (3), and an oxophthalazin-2(1 H)-yl)acetohydrazide (13) are utilized as precursors to construct a novel series of phthalazinones bearing various ...
