Abstract

The solid-supported iodobenzoic acid derivatives 8-10 were coupled with a range of organozinc reagents 1-4 under palladium(o) catalysis. The coupled products released by acidic cleavage with TFA were obtained in high purities after recrystallization. Analogous coupling of solid-supported (E)- and (Z)-3-iodoacrylic acids 18a, 18b, 19 and 20 gave (E)- and (Z)-α,β-unsaturated acids and amides 21-27 stereospecifically.
