The present invention concerns highly water-soluble phenoxazines dyes of formula (I) wherein R1, R2, R3, R4, R5 and R6 have the meaning defined in the claim, with improved photochemical properties, low toxicity, and favourable solubility in water. It also concerns a method for their preparation.
Laccase-Mediated Synthesis of Novel Substituted Phenoxazine Chromophores Featuring Tuneable Water Solubility
oxidative coupling reactions. Yet, laccases remain rarely described as biocatalysts in organic synthesis. This paper describes the chemical preparation of original sulfonated aminophenol substrates and their enzyme‐mediated dimerisation into phenoxazinechromophores that featuretuneablewatersolubility as a function of the sulfonyl substituent. The scope and limitations of the biocatalysed synthetic
