1. SUMMARY
In this paper, several piperazinediones containing naphthalen moiety were synthesized as (cyclo)tryprostatin analogues by Pictet-Spengler reaction through acylation of the piperidine nitrogen, then condensation with primary amines such as n-propyl and n-butyl amine. These compounds were further treated with primary amines to afford the corresponding diketopiperazines.
Keywords: Pictet-Spengler, piperazinedione, diketopiperazines, activity, (cyclo)tryprostatin
2. INTRODUCTION
Piperazinediones are the class of truly ubiquitous structures involved in the regulation of a wide variety of biological processes [1, 2]. The broad range of bioactivities of these molecules has led to their description as ‘privileged structures’[3,4].
