Synthesis of bioactive 1-alkyl-1H-naphtho[2,3-d][1,2,3]triazole-4,9-diones and N-aryl-2-aminomethylene-1,3-indanediones using water as the solvent
摘要:
Through a [2+3] cycloaddition reaction, a new environmentally friendly method was developed to enable the synthesis of bioactive 1-alkyl-1H-naphtho[2,3-d][1,2,3]triazole-4,9-diones and N-aryl-2-aminomethylene-1,3-indanediones using water as the solvent with good yields and minimum requirement of purification. This new green synthetic protocol is simple and suitable for scale-up synthesis. (C) 2014 Elsevier Ltd. All rights reserved.

Die in Teil 1 dargestellten (2‐Chlor‐1,3‐dioxo‐indan‐2‐yl)‐methansulfonate 1 lieferten mit Phosphorpentachlorid teilweise die Sulfonylchloride 2, aber auch das Abbauprodukt 3 sowie das Bis‐acyl‐ketendichlorid 7. Mit Aminen reagierte 2 nicht zu den Sulfonamiden 9, sondern zu den 2‐Amino‐methyliden‐1,3‐indanionen 10.

In this study, the cerium(III) trifluoromethanesulfonate–catalyzed cycloaddition of 1,4-naphthoquinone with functionalized azides in aqueous solutions was used to synthesize naphtho[2,3-d][1,2,3]triazole-4,9-dione derivatives. Moreover, our method boasts scalability and completes the synthesis of two key biological compounds. Our method's advantages are environmentally friendly reaction conditions
