A simple route for the synthesis of new polyfluorinated 4-thiazolidinones and 1,4-bis(4-thiazolidinone)phenylenes was achieved from one-pot three-component reaction of fluorinated aniline, mono- and dialdehyde and thioglycolic acid followed by fluorination with trifluoroacetamide and 4-fluorobenzaldehyde. Also, some new fluorinated alpha-aminophosphonates, 1,4-bis(alpha-aminophosphonate)phenylenes and their corresponding acids were synthesized via one-pot three-component reaction of fluorinated aniline, mono- and dialdehyde and diethyl phosphite followed by fluorination with trifluoroacetic anhydride. All the synthesized compounds were screened for their antifungal activity against Alternaria alternate and Fusarium oxysporium. Also, their effects on the enzymatic effect of cellobiase produced from Alternaria alternate and Fusarium oxysporium were estimated. Compounds that have trifluoromethyl groups recorded good inhibition against the fungal strains and also enhanced the enzymatic effect of cellobiase. .
