Herein, we report a bioinspired approach to the synthesis of 1,4-benzothiazines by drawing inspiration from the biosynthesis of pheomelanin pigments (pheomelanogenesis). In this context, general conditions for the regioselective coupling reaction between

Red Hair 1,4-Benzothiazines: from Human Pigmentation to Functional Dyes
, 2014 The 2H-1,4-benzothiazines represent a unique group of naturally occurring heterocyclic compounds, which derive biogenetically from tyrosine and cysteine via a mutation-induced deviation of the melanin pathway to provide the core structure of the red ...
