An unexpected triethylsilane-triggered rearrangement of thioaurones to thioflavonols under SPPS conditions
Artikel i vetenskaplig tidskrift, 2008
Thioaurones are converted to a mixture of thiaindenes and thioflavonols when exposed to reaction conditions employed in SPPS, that is, treatment with trifluoroacetic acid in the presence of triethylsilane.
