Naphthalene derivatives are substructures of many natural compounds,2 synthetic drugs,3 dispersants, and synthetic dyes and pigments.1 Examples of occurrences and applications of the naphthalene core are given in Figure 1. Compounds 1 and 2 were recently identified as active components of Pentas parvifolia, a plant used in therapy.2b Nabumetone 3 and Terbinafine 4 are examples of commercialized naphthalene-based drugs, while Mitonafide 54 exhibiting anti-cancer activity is at the clinical trial stage. Naphthalenes are also used in dye industry (e.g., compound 6) and applied research.5

In view of a high relevance of the naphthalene moiety in drug discovery and materials development, it is of importance to design novel naphthalene-based building blocks with controllable substitution patterns and variable functional groups. In response to this vivid drug discovery market demand Life Chemicals has produced its original functionalized naphthalenes, with some of their examples being presented below.
