  The Double Reduction of Cyclic Sulfonamides for the Synthesis of (4S-Phenylpyrrolidin-2R-yl)methanol and 2S-Methyl-4S-phenylpyrrolidine

  摘要：

  The synthesis of (4S-phenylpyrrolidin-2R-yl)methanol and 2S-methyl-4S-phenylpyrrolidine has been achieved via the double reduction of their cyclic sulfonamide precursors which themselves were prepared following the stereoselective intramolecular Heck reaction of a chiral pool derived 2,5-dihydropyrrole. We have recently described a process whereby cyclic aryl sulfonamides, such as 2, are reductively ring-opened to furnish amino products in which the aryl group is incorporated in the final compound. (Evans, P.; McCabe, T.; Morgan, B. S.; Reau, S. Org. Lett. 2005, 7, 43.) The precursors for this reaction were assembled using an intramolecular Heck reaction followed by reduction of the alkene. Overall, this sequence represents an efficient means to construct molecules of this type in which the aryl sulfonyl moiety acts as both an N-protecting group and as an aryl donor. Use of Benkeser's stronger reducing conditions enables molecules such as 4 to be prepared in which both the sulfonamide functional group and the aromaticity of the aryl substituent have been destroyed.

  A particularly general protocol for the organocatalytic asymmetric Michael addition of nitroalkanes to α,β-unsaturated enones is reported. The Michael reaction proceeded smoothly and provided the desired adducts in moderate to excellent yields (55–99%) and good to excellent enantioselectivities (65–99% ee). The addition of readily available achiral base significantly enhanced the reactivity without

  complex for 1‐alkylaminopentenes diminishes resolution efficiency. Nevertheless, the relative cyclization rate for the two diastereomeric substrate–catalyst complexes remains in a typical range of 7–10:1. Plausible attractive π interactions between the aryl substituent and either the metal center or the aromatic system of the bis(triarylsilyl)‐substituted binaphtholate ligand may explain increased stability

  使用3，3′-双（三芳基甲硅烷基）取代的邻萘二甲酸稀土金属配合物研究了手性氨基烯烃通过加氢胺化反应的动力学拆分。1-芳基氨基戊烯的拆分具有较高的效率和较高的反式-非对映选择性，而1-烷基氨基戊烯的拆分过程则随着脂肪族取代基的空间需求的增加而降低了拆分效率。通过使用对映纯底物和（R）-或（S）-萘甲酸酯催化剂显示，分离效率的差异源于科廷-汉米特预平衡的变化。尽管1-芳基氨基戊烯偏爱匹配的底物-催化剂配合物，但对于1-烷基氨基戊烯偏爱错配的底物-催化剂配合物却降低了分离效率。然而，两种非对映异构底物-催化剂复合物的相对环化率通常在7-10：1的范围内。芳基取代基与双（三芳基甲硅烷基）取代的邻萘二甲酸酯配体的金属中心或芳族体系之间可能存在的吸引性π相互作用可能解释了匹配的底物-催化剂配合物的稳定性提高。顺便说一句，甲氧基甲基（MOM）取代的氨基戊烯3 g由于MOM取代基的螯合性质，它也表现出对匹
