  Amino-Protecting Groups Subject to Deblocking under Conditions of Nucleophilic Addition to a Michael Acceptor. Structure−Reactivity Studies and Use of the 2-(tert-Butylsulfonyl)-2-propenyloxycarbonyl (Bspoc) Group

  摘要：

  A new type of amino-protecting group is described in which a Michael acceptor is incorporated into the protectant so that treatment with a nucleophile will trigger deblocking. Comparison of various Michael accepters showed that for several key electron-withdrawing groups, the order of reactivity was C6H5SO2 > Me3CSO2 > COOEt > CsH5SO > C(6)H(4)NO(2-)p. The reactivity of the nucleophile. (e.g., primary and secondary aliphatic amines) followed an order related to both intrinsic basicity and steric effects. beta-Substituents in the Michael acceptor caused significant retardation of the deblocking process. The Bspoc function was chosen for initial elaboration into a practical system for use in peptide synthesis. Bspoc amino acid chlorides were used as coupling agents and silica-tethered secondary amines as deblocking agents. With the latter, deblocking occurs cleanly and no byproducts remain in the organic solvent in which the deblocking is executed.

  A highly efficient one-step copper(I)-catalyzed method for the synthesis of α-sulfenylated carbonyl compounds from propargylic alcohols and aryl thiols in aqueous media is described. A variety of α-sulfenylated carbonyl compounds can be synthesized in good to excellent yields. The catalyst has been successfully recycled up to 4 times without any loss of activity in an aqueous medium.

  Gold(I)‐chloride‐catalyzed synthesis of α‐sulfenylated carbonyl compounds from propargylic alcohols and aryl thiols showed a wide substrate scope with respect to both propargylic alcohols and aryl thiols. Primary and secondary aromatic propargylic alcohols generated α‐sulfenylated aldehydes and ketones in 60–97 % yield. Secondary aliphatic propargylic alcohols generated α‐sulfenylated ketones in yields

  氯化金催化由炔丙醇和芳基硫醇合成 α-磺基化羰基化合物，对于炔丙醇和芳基硫醇显示出广泛的底物范围。伯芳族炔丙醇和仲芳族炔丙醇生成 α-磺酰化醛和酮，产率为 60-97%。仲脂肪族炔丙醇生成 α-磺酰化酮，产率为 47-71%。研究了不同的金源和配体效应，结果表明氯化金（I）的产物收率最高。实验和理论研究表明该反应分两个单独的步骤进行。芳基硫醇对炔丙醇的三键进行初始区域选择性攻击而生成的亚磺酰化烯丙醇经过分离、评估后发现是该反应的中间体。氘标记实验表明，炔丙醇和芳硫醇的质子转移到产物的3位，醇的氢化物转移到产物的2位。密度泛函理论（DFT）计算表明，观察到的芳基硫醇对炔丙醇2位的攻击的区域选择性是由低能五元环原脱气过渡态决定的，而不是由应变的四元环过渡态决定的发现在 3 号位置进攻的状态。实验数据和DFT计算支持反应的第二步是通过与氯化金(I)配位的质子供体对磺基化烯丙醇的双键进行质子化来引发的。这反过来又允许
