1‐(Acetylamino)thioxanthones and Derivatives: Synthesis From 1‐Halogenothioxanthones and Biological Properties

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 30, 12 August 2026.
The conversion of 1‐halogenothioxanthones into 1‐(acetylamino) derivatives and their NaH‐mediated cyclization have been optimized. This rapid method yields thiochromeno[4,3,2‐de]quinol‐2‐ones that exhibit promising in vitro anticancer activity.
