Synthesis of Novel Crown Ether-Squaramides and Their Application as Phase-Transfer Catalysts
This work presents the synthesis of six new phase-transfer organocatalysts in which the squaramide unit is directly linked to the nitrogen atom of an aza-crown ether. Four chiral skeletons, namely hydroquinine, quinine, cinchonine (cinchonas), and α-<span style="font-variant: small-caps;&quo...
