Ugi Cascade Sequence for the Construction of 3-Pyrrolin-2-one Scaffolds: Anti-proliferation in Prostate Cancer Cells.

Abstract

Herein, a small series of 3-pyrrolin-2-ones was efficiently synthesized through a three-step Ugi cascade sequence. This method features readily available substrates, simple aqueous workup procedures and good yields, dramatically improving generality of reaction. Importantly, the newly product N-benzyl-2-(3-(4-chlorophenyl)-4-methyl-2-oxo-2,5-dihydro-1H-pyrrol-1-yl)-2-phen-ylacetamide exhibited potent anti-proliferation in prostate cancer cell line through G1/S cell cycle arrest and targeted in PI3K/AKT/TSC2 signal pathway.
