[摘要]:The synthesis of substituted styrenes, e.g. I (R1 = R2 = n-Pr), was achieved by ring-closing enyne metathesis (RCEM)/elimination of enyne substrates, e.g. II. The synthetic approach was also effective for a different type of enyne substrate III, yielding corresponding styrene I (R1 = Ph, R2 = Me). |
