The synthesis, in vitro evaluation, and structure-activity relationship studies of homoallylamines and related derivatives acting as antifungalagents are reported. Among them, compounds N-(4-bromophenyl)-N-(2-furylmethyl)amine and N-(4-chlorophenyl)-N-(2-furylmethyl)amine reported here exhibited remarkable antifungal activity against dermatophytes. Theoretical calculations allow us to determine the

A series of 1- and 3-halo-substituted isoindolo[2,1-a]quinolines were obtained by means of electrophilic cyclization of methallyl- and allyl-substituted isoindolo-7-carboxylic acids. The influence of halogen atoms on the stereochemistry of the formation of key intermediates, 3a,6-epoxyisoindoles, was studied.
The straightforward synthesis of new isoindolo[2,1-a]quinolinederivatives from 2,4-disubstituted 1,2,3,4-tetrahydroquinolines bearing a furan fragment via the intramolecular Diels-Alder reaction is reported. The synthesis of key precursors was realized with excellent levels of diastereoselectivity either by Povarov reaction or by a multicomponent condensation approach.

hetaryl fragments were easily prepared from corresponding aldimines derived from commercially available aromatic aldehydes and anilines. 2-Furyl substituted anilines showed very good antifungal activities against dermatophytes, particularly against Trichophyton rubrum (MIC=3.12-6.25microg/mL). In addition, all active compounds, 45-47, 73, and 74, were tested for cytotoxic activities against breast (MCF-7)
