    摘要:
    已证明手性N-膦酰基亚胺是在方便条件下与丙烯酸酯进行不对称氮杂-Morita-Baylis-Hillman(aza-MBH)反应的有效亲电子受体。以原子经济的方式,以高收率(高达99.4%)和非对映选择性(高达> 99:1 dr)生成了30个β-氨基丙烯酸酯实例。已证明该合成遵循GAP(基团辅助纯化)化学方法,即,无需使用色谱法或色谱法,只需用己烷/乙酸乙酯(v / v,10/1)洗涤粗产物即可简单地获得纯产物。重结晶。还进行了DFT计算,以支持考虑非对映选择性高的不对称诱导模型。

  • N,N-Diisopropyl-N-phosphonyl imines lead to efficient asymmetric synthesis of aziridine-2-carboxylic esters

    DOI:10.1039/c3ob40251g
    日期:——
    Highly diastereoselective asymmetric synthesis of chiral aziridine-2-carboxylic esters is reported for 20 examples with good yields (51–87%) and excellent diastereoselectivities (>99 : 1 dr for most cases). The modified N-phosphonyl imines have proven to be superior to previous imine auxiliaries for the aza Darzens reaction by using a secondary isopropyl group to replace the primary benzyl group for
    据报道,手性氮丙啶-2-羧酸酯的高度非对映选择性不对称合成有 20 个实例,具有良好的产率(51-87%)和出色的非对映选择性(大多数情况下 >99:1 dr)。通过使用仲异丙基取代N , N的伯苄基,已证明改性N - 膦酰基亚胺在 aza Darzens 反应中优于以前的亚胺助剂。-二基保护。同时,发现在 4 Å 分子筛存在的情况下,在该温度下将预冷的亚胺溶液在 -78 °C 下缓慢加入到预先形成的 β-化烯醇混合物中的特殊操作对产率至关重要和非对映选择性。本方法可以提供对 β-羟基α-氨基酸和其他重要基构建块的简单和通用的访问。
  • Asymmetric Carbamoyl Anion Additions to Chiral <i>N</i>-Phosphonyl Imines via the GAP Chemistry Process and Stereoselectivity Enrichments
    作者:Cole W. Seifert、Suresh Pindi、Guigen Li
    DOI:10.1021/jo5024443
    日期:2015.1.2
    Carbamoyl anions were found to smoothly react with chiral N-phosphonyl imines in toluene at -78 degrees C to r.t. using LiHMDS as the base. Group-assisted purification (GAP) has been utilized to give the pure amides without using column chromatography or recrystallization. The asymmetric reaction resulted in chiral N-phosphonyl amino amides with good to excellent yields (71-99%) and good crude diastereoselectivities (dr 84:16-95:5). In this GAP procedure, the crude solids are washed with diethyl ether to afford the pure products, as revealed by H-1 NMR analysis; GAP washing consistently increases the diastereopurity of the products, resulting in excellent diastereoselectivities, often with final dr > 99:1. Interestingly, the diastereoenriched products can be obtained either in the ether solution or as the suspended solid, depending on the substrate.
  • Chiral N-phosphonyl imine chemistry: Asymmetric synthesis of α,β-diamino esters by reacting phosphonyl imines with glycine enolates
    作者:Teng Ai、Guigen Li
    DOI:10.1016/j.bmcl.2009.03.001
    日期:2009.7
    Chiral phosphonyl imines attached with N-isopropyl protection group were found to react with lithium glycine enolates under convenient conditions to give alpha,beta-diamino esters. Thirteen examples have been examined in good to excellent chemical yields (85-97%) diastereoselectivity (up to 99% de). By treating with HBr at room temperature, the chiral auxiliary can be readily removed and recycled. The absolute structure has been unambiguously determined by converting a product to a known sample.
