Wc. Shakespeare et al., An efficient synthesis of a 4 '-phosphonodifluoromethyl-3 '-formyl-phenylalanine containing Src SH2 ligand, BIOORG MED, 9(21), 1999, pp. 3109-3112
A CuBr-mediated, regioselective cross-coupling between methyl 2,5-diiodoben
zoate (4) and [(diethoxyphosphinyl)difluoromethyl]zinc bromide is reported.
Palladium-catalyzed incorporation of an amino acid side chain, followed by
subsequent modifications resulted in the rapid construction of 2. Compound
2 was designed to engage Cys188 of the Src SH2 domain, however, this was n
ot observed spectroscopically. (C) 1999 Elsevier Science Ltd. All rights re
