    1,1-Dialkyl-3-iodoallenes were prepared in good yield from 1,1-dialkylprop-2-yn-1-ols and 45% hydriodic acid in the presence of copper(I) iodide. Several 1-bromo- and 1-chloro-alk-1-yn-3-ols were converted by hydrogen bromide–copper(I) bromide or thionyl chloride into the corresponding 1,1-dibromo-, 1-bromo-1-chloro- or 1,1-dichloro-allenes. The mechanism of the reaction is discussed and the spectroscopic

    l-Tryptophan reacts with α,β-acetylenic γ-hydroxy nitriles, chemo- and regiospecifically, under mild, green conditions via a hydroamination-type process involving the primary amine group. The hydroxycyanopropanyl substituent of the initial adducts undergoes cyclization to afford a 2,5-dihydro-5-iminofuranyl moiety. Several novel amino acids are obtained in almost quantitative yields (95-98%), which exist

    synthesized from unprotected 1-bromopropargyl alcohols using a copper(II) catalyzed coupling reaction. In the second step, the previously prepared ynamides were transformed directly to allenes through a [2,3]-sigmatropic rearrangement of propargyl phosphites. This efficient method led to the formation of a series of α-amino allenephosphonates with diverse substituents on the amine, the phosphonate, and the
    从受保护的胺,炔丙醇亚磷酸酯容易地分两步制备α-烯丙基膦酸酯。首先,使用(II)催化的偶联反应,由未保护的1-丙醇合成乙酰胺。在第二步中,通过炔丙基亚磷酸酯的[2,3]-σ重排将先前制备的炔酰胺直接转化为亚丙基。这种有效的方法导致形成一系列在胺,膦酸酯和丙二烯基团上具有不同取代基的α-丙二烯膦酸酯。
