Trimethylammonium veratraldehyde triflate was synthesized and used as a precurser for the synthesis of 6-Fluoro-L-DOPA by using the chiral phase-transfer catalyst
O-Allyl-N-(9)-anthracenylcinchonidinium bromide which was also synthesized in this study. Based on these
6-Fluoro-L-DOPA was prepared with acceptable radiochemical yield (10±3)% in short synthesis time (80min)
