Three synthetic strategies for the construction of tert-butyl (E)-3-arylprop-2-en-1-ol carbonates are described. Complementary approaches employing Suzuki-Miyaura coupling and cross-metathesis reaction gave moderate yields of the title compounds in one-step, both methods are suitable for high-throughput and parallel chemistry. A detailed investigation into the Suzuki-Miyaura coupling reaction is provided along with the studies on the synthesis of pinacolyl 1-(tert-butyloxycarbonyl)propenol-3-ylboronate, the key building block. Conventional synthesis of the title compounds via the Horner-Wadsworth-Emmons reaction as a key step in a three-step-one-purification protocol was optimized and the results are compared with those of the latter reactions.
