Fluorocinnamic acid

There were two potential starting materials for Trost s Mo chemistry (Scheme 2.7). The first approach utilized the commercially available 3-fluorocinnamic acid (4). However, reduction of 4 did not proceed well with various reducing agents and provided the desired allylic alcohol 28 in only mediocre yield. Alternatively, 3-fluorobenzaldehyde (29) was used as the starting material. Vinyl Grignard addi-... [Pg.50]

Berlin and Widholm (31) selected carrot and tobacco cells resistant to PFP. In contrast with the Ccirrot line, which showed the expected increases in free Phe, the PFP-resistant cells (TX4) had almost normal levels of Phe, but did show dramatic increases in phenolics apparently due to a 10- to 20-fold rise in phenylalanine ammonia lyase (PAL) activity as compared to control cells (TXl). It was suggested that this cell line was resistant to PFP due to the higher PAL activity, which could detoxify PFP by conversion to p-fluorocinnamic acid. If this method could be generally applied, it would allow for the positive selection of cell strains overproducing a specific class of secondary compounds. [Pg.73]

Various fluorinated polymershave been studied, and the interactions of p-fluorocinnamate with poly(N-substituted)acrylamides, fluoro-benzyloxycarbonyl and 2-(4-fluorophenyl)-2-propyloxycarbonyl amino acids with cross-linked polystyrene, and fluoride ion mobility in ion exchange membranes have been investigated. [Pg.386]
