| 英文摘要 | bronsted acid-mediated annulation of internal olefins -oxo ketene dithioacetals to pyrroles was efficiently achieved to afford cyclopenta[b]pyrroles. a pair of bronsted acids with acid strengths, that is, trifluoroacetic acid, and para-toluenesulfonic acid hydrate, were applied to promote the annulation reactions. the resultant products were readily oxidized to sulfones by meta-chloroperoxybenzoic acid. subsequent treatment with 1,8-diazabicyclo[5.4.0]undec-7-ene gave desulfurized terminal olefins or [2+2] cycloaddition products from the desulfurized olefin intermediates. the present protocol provides facile access to structurally diverse cyclopenta[b]pyrrole derivatives under mild conditions. |
