TL;DR: Synthesis of tetracyclic and pentacyclics from 2-aminothiazole derivatives (1, 4, 10 and 13) with simple methodology in fairly good yields were obtained in this article.
Abstract: Syntheses of tetracyclic and pentacyclic thiazolopyrimidinones (3, 6, 11 and 16) were obtained from the corresponding 2-aminothiazole derivatives (1, 4, 10 and 13) with simple methodology in fairly good yields.

TL;DR: Evaluation of the synthesized compounds for cytotoxicity against KB, HeLa, MKN-28 and MCF-7 cell lines showed that the 22-alkynylcyclodinorchoenones possessing hydroxylethyl and hydroxylmethyl mono-substituted side chain at the end of alkynyl group have significantly inhibition activity.
