    developed to construct diversely substituted imidazo[1,2-a]pyridines and benzimidazo[1,2-a]pyridines in good to excellent yield. The advantage of this unique [4 + 2]-annulation lies in the employment of readily accessible starting materials, Morita–Baylis–Hillman acetates of acetylenic aldehydes as C4 synthons, and simple imidazoles or benzimidazoles as C2 synthons.

    One-pot synthesis of substituted cyclopentenes was accomplished through a copper-mediated [4 + 1]-annulation of active methylene compounds with Morita–Baylis–Hillman (MBH) acetates of acetylenic aldehydes. The reaction sequence involves the cascade allylic substitution/5-exo-dig-carbocyclization, which was effective in providing methylene, alkylidene as well as arylidene cyclopentenes.

    日期:2015.2.20
    Synthesis of substituted pyridines through a novel aza-annulation of 2-en-4-ynyl azides, derived from MBH-acetates of acetylenic aldehydes, is described. A variety of enynyl azides having aryl, heteroaryl, and alkyl groups on the alkyne functionality successfully participated in the Ag-mediated annulation reaction to provide the corresponding 3,6-disubstituted pyridines. I2-Mediated cyclization was
