  Achieving Control over the Branched/Linear Selectivity in Palladium-Catalyzed Allylic Amination

  摘要：

  Palladium-catalyzed reaction of unsymmetrical allylic electrophiles with amines gives rise to regioisomeric allylic amines. We have found that linear products result from the thermodynamically controlled isomerization of the initially formed branched products. The isomerization is promoted by protic acid and active palladium catalyst. The use of base shuts down the isomerization pathway and allows for the preparation and isolation of branched allylic amines. Solvent plays a key role in achieving high kinetic regioselectivity and in controlling the rate of isomerization. The isomerization can be combined with ring-closing metathesis to afford the synthesis of exocyclic allylic amines from their endocyclic precursors.

  A quinoline-oxazoline compound having the formula: where one of X 1 and X 2 is N and the other is C and one of R1, R2 and R3 is Z wherein Z is an oxazoline radical having the formula such that when X 1 is N R2 is Z and R1 is absent, and when X 2 is N either R1 or R3 is Z and R2 is absent. R1 and R3 through R12 are independently H or a pendant moiety which does not interfere with coordination of either N in the quinoline compound with a coordination center. These compounds can be complexed with a suitable coordination center such as catalytically active palladium and can be highly useful in catalytically oxidizing alkenes with high regioselectivity.

  The C-H activation of silyl ethers by means of rhodium carbenoid-induced C-H insertion represents a very direct method for the stereoselective synthesis of silyl-protected beta-hydroxy esters. The reaction can proceed with very high regio-, diastereo-, and enantioselectivity and represents a surrogate to the aldol reaction. The reaction is catalyzed by the rhodium prolinate complex Rh(2)(S-DOSP)(4)

  借助于铑类胡萝卜素诱导的CH插入而实现的甲硅烷基醚的CH活化代表了一种立体选择性合成甲硅烷基保护的β-羟基酯的非常直接的方法。该反应可以以非常高的区域，非对映和对映选择性进行，并且代表了醛醇缩合反应的替代物。反应由脯氨酸铑络合物Rh（2）（S-DOSP）（4）催化。高化学选择性的关键要求是使用供体/受体取代的类胡萝卜素，例如衍生自芳基重氮乙酸甲酯的那些。可以使用多种甲硅烷基醚，例如烯丙基甲硅烷基醚，四烷氧基硅烷，甚至简单的三甲基甲硅烷基烷基醚。通常，CH活化优先发生在亚甲基位置，因为反应性受空间和电子效应之间的微妙平衡控制。
