title: Synthesis and preliminary biological screening of sterol analogues as new antifungal agents against plant pathogens.
abstract: In this paper we report the synthesis of a new family of sterol analogues that have two amidic bonds on the side chain. These azasterols were obtained by a straightforward procedure including an Ugi condensation that allows the facile attachment of a polyfunctionalized side chain into the steroidal framework. Some of the new compounds showed an interesting inhibitory effect on the growth of two pathogenic fungi involved in plant diseases.
