The synthesis and fluorescence profile of novel thalidomide analogues

Abstract

Herein we describe the synthesis of various simple N-alkyl thalidomide derivatives in order to determine their fluorescence excitation and emission profile. Following this, a series of more complex fragments were attached through a Huisgen 1,3-dipolar cycloaddition providing a more diverse fluorescence profile. A thalidomide azide derivative was also found to be particularly reactive in a copper-free click reaction with two known cyclooctynes. © 2015 Elsevier Ltd.
