  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.

  This invention relates to compounds of the formula: wherein R is an electron withdrawing group; R₁ is H or COZ; X₁ and X₂ are independently H, lower alkyl, aryl, aryl lower-alkyl or polystyrene or R and X₁ taken together with the carbon atoms to which they are attached form a ring containing from 4 to 15 ring carbon atoms and may contain up to 2 heteroatoms, wherein the heteroatoms are O, S, or N; and Z is an amino acid residue, a peptide residue or a leaving group. The compounds of the present invention are adaptable as blocking or protecting groups for an amine composition useful in peptide synthesis. The present invention is also directed to a method of protecting an amino group of an organic molecule during a reaction which modifies a portion of the molecule other than the protected amino group.

  本发明涉及式中的化合物： 其中 R 是取电子基团； R₁ 是 H 或 COZ； X₁ 和 X₂ 独立地为 H、低级烷基、芳基、芳基低级烷基或聚苯乙烯，或 R 和 X₁ 与它们所连接的碳原子一起形成一个环，该环含 4 至 15 个环状碳原子，最多可包含 2 个杂原子，其中杂原子为 O、S 或 N；以及 Z 是氨基酸残基、肽残基或离去基团。本发明的化合物可用作肽合成中胺类组合物的封端或保护基团。本发明还涉及一种在反应过程中保护有机分子氨基的方法，该反应改变了分子中除受保护氨基以外的部分。
