By the reaction of furan-2-carboxylic acids and furfural with diazonium salts 1a-j the arylfuran-2-carboxylic acids 4a-e and 5-arylfuran-2-carbaldehydes 5a-f were synthesized. Acids 4a-e were transformed into appropriated acylchlorides 6a-e and were used for preparation of 4-(5-aryl-2-furoyl)morpholines 7a-e. 4-[(5-Aryl-2-furyl)carbonothioyl]morpholines 8a-f were prepared from aldehydes 5a-f by using Willgerodt-Kindler reaction. The structures of the obtained compounds were confirmed by 1H NMR

The antimicrobial activities of synthesized compounds 7a-e and 8a-f were investigated and the compounds with high activity against C. neoformans ATCC 208821 were identified.
