摘要

The Suzuki-coupling reaction of 2-(dihydroxyboryl)-3, 4-dimethyl-2-cyclopenten-1-one (1) and 2-(dihydroxyboryl)-3-methyl-2-cyclopenten-1-one (2) with 2-bromoaniline derivatives affords cyclopentenone compounds (3–8) from which cyclopentadiene compounds, 4, 6-R′ 2-2-(2, 5-Me2C5H3) C6H2NH2 (9–11) and 4, 6-R′ 2-2-(2, 3, 5-Me3C5H2) C6H2NH2 (12– 14) are prepared. After sulfonation of the–NH2 group with p-TsCl, metallation is carried ...
