  • Copper-catalyzed regiodivergent 1,4- and 1,6-conjugate silyl addition to diendioates: access to functionalized allylsilanes
    作者:Tanveer Ahmad、Qi Li、Sheng-Qi Qiu、Jian-Lin Xu、Yun-He Xu、Teck-Peng Loh
    DOI:10.1039/c9ob01086f
    日期:——
    A copper-catalyzed regioselective 1,4- and 1,6-conjugate addition of a silyl reagent to diendioates was established. Various 1,4- and 1,6-protosilylation products were obtained in good yields and with high regioselectivity via tuning the ligands used in the reactions. This protocol has provided a simple and efficient method for the synthesis of multisubstituted functionalized allylsilanes.

  • Mechanism of cyclocondensation of isoprenoid acyclic ?,?-enals with monoethyl malonate under the conditions of the Knoevenagel reaction
    作者:A. G. Nigmatov、�. P. Serebryakov
    DOI:10.1007/bf00961358
    日期:1991.5
    It was shown that the formation of the di- and trisubstituted derivatives of 1.3-cyclohexadiene-1-carboxylic acid during the condensation of 3-methyl-2-butenal, citral, and farnesal with monoethyl malonate in the presence of secondary amines takes place through the enamines corresponding to these aldehydes, which add to the monoesters of the respective alkenylidenemalonic acids (the "normal" products of the Knoevenagel reaction) by a mechanism of [4 + 2]-cycloaddition. The free carboxyl group in the dienophile is required for the spontaneous transformation of the intermediate [4 + 2]-cycloadducts into the derivatives of cyclohexadiene-1-carboxylic acid in which the catalyst of the process (the secondary amine) is regenerated.
