The total synthesis of the 18,18,18-trifluoro analogue (FDNT) of 14-dehydro-19-nortestosterone (DNT) was performed using the intramolecular Diels-Alder reaction of an ortho-quinodimethane. Unlike 18,18,18-trifluoro-19-nortestosterone (FNT), FDNT showed in vitro and in vivo biological properties (binding affinity for the androgen receptor and growth stimulation of ventral prostate and seminal vesicles) comparable with its unfluorinated counterpart (DNT). The diverging behaviour of FNT and FDNT is tentatively ascribed to a difference in ring-D geometry.
