    摘要:
    开发了多种亲核试剂到衍生自1,8-二羟基萘(DHN)的酰基乙烯酮缩醛中的共轭加成物,以形成其3-氧代烷-1-酮缩醛。最初的酰基乙烯酮缩醛是通过将DHN的双oxa-Michael加成至1-bromo-1-propyn-3-ones制备的。在碱性条件下引入了亲碳亲核试剂,包括有机铜试剂和活性亚甲基化合物,以及杂原子亲核试剂。该方法适用于合成螺旋藻A。建议的结构与真实的天然产品的结构不符。

    Diels–Alder Construction of Regiodifferentiated meta-Amino Phenols and Derivatives
    摘要:
    Synthetic access to regiodifferentiated meta-amino phenols is described. The strategy relies upon distinct deprotonation conditions to afford regioisomeric thermodynamic and kinetic dienes that undergo a tandem Diels-Alder and retro-Diels-Alder sequence with assorted acetylenic dienophiles to afford a range of aromatic products.

    The first representatives of a previously unknown class of highly reactive functionalized pyrrole compounds, 3-(pyrrol-2-yl)propiolaldehydes, have been synthesized by the transition metal-free, mechanoactivated ethynylation of pyrroles with 3-iodopropiolaldehyde using a solid K2CO3 medium under mild conditions (room temperature, 4 h) in yields of up to 71%.

    menthofuran, a naturally abundant compound, it has been shown for the first time that the furan ring can be readily cross-coupled with acylhaloacetylenes in the solid Al2O3 powder at room temperature to afford the corresponding 2-ethynyl derivatives in up to 88% yield. The reaction represents a ring closing/ring opening process that includes reversible formation of the intermediate cycloadducts further
    以天然丰富的化合物薄荷呋喃为例,首次证明呋喃环可以在室温下与固体Al 2 O 3粉末中的酰卤乙炔很容易地交叉偶联,得到相应的2-乙炔基衍生物产率高达 88%。该反应代表闭环/开环过程,包括中间体环加合物的可逆形成,进一步产生乙炔衍生物并消除HHal。

    A conjugate addition of diverse nucleophiles to acylketene acetals derived from 1,8-dihydroxynaphthalene (DHN) is developed for the formation of its 3-oxoalkan-1-one acetals. The initial acylketene acetals are prepared via double oxa-Michael addition of DHN to 1-bromo-1-propyn-3-ones. Carbonucleophiles, including organocopper reagents and active methylene compounds, and heteroatom nucleophiles were
