Abstract

1. Introduction. – Natural and non-natural diaryl sulfides (diaryl thioethers) are of pharmacological relevance and have been isolated as natural products (for dibenzo- thiophenes, see [1a]; for lissoclinotoxins (varacins), see [1b] [1c] [1d]; for lissoclibadins, see [1e][1f]; for cyclo(penta-1,4 -phenylenesulfide) and cyclotetra(p-phenylenesul- fide), see [1g]; and for natural products isolated from Streptomyces griseus, see [1h]). For example, fluorinated diaryl sulfides have been ...
