for the preparation of N-substituted 2-phopshorylpyrrolidines from readily available 4,4-diethoxybutan-1-amine derivatives and P (III) acid chlorides is described. The presented method benefits from simple reaction and work-up procedures, mild reaction conditions, avoids protecting group introduction-removal stages and provides a straightforward access to target compounds. In vitro cytotoxicity studies
A library of novel2-(het)arylpyrrolidine-1-carboxamides were obtained via a modular approach based on the intramolecular cyclization/Mannich-type reaction of N-(4,4-diethoxybutyl)ureas. Their anti-cancer activities both in vitro and in vivo were tested. The in vitro activity of some compounds towards M-Hela tumor cell lines was twice that of the reference drug tamoxifen, whereas cytotoxicity towards

AbstractHerein we report the synthesis of previously unknown 2-arylpyrrolidine-1-carboxamides containing aminophenol moiety via a novel approach developed by us, namely, acid-catalyzed cyclization of (4,4-diethoxybutyl)ureas in the presence of 3-aminophenol. The proposed approach benefits from mild reaction conditions, use of inexpensive and common solvents and catalyst, and allows to obtain target

Acid-catalyzed reaction of phenols with 1-(4,4-diethoxybutyl)urea derivatives gave new 2-arylpyrrolidines containing 4-bromoresorcinol and hydroquinone fragments. The described reaction is advantageous due to its mild conditions and no necessity of using expensive or toxic catalyst.
