Abstract
In the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), 9-triptycylisothiocyanate has been synthesized in 91% yield from carbon disulfide and sterically hindered 9-triptycylamine at room temperature. 9-Triptycylisothiocyanate can be further converted to 1-benzyl-3-(9-triptycyl)thiourea. (10-Amino-9-triptycyl)carboxylic acid has also been successfully synthesized via a three-step route starting from methyl 10-nitroanthracene-9-carboylate. Its amino and carboxylic groups can undergo acetylation and amidation, respectively.
