  Highly Regioselective Thiocarbonylation of Allylic Alcohols with Thiols and Carbon Monoxide Catalyzed by Palladium Complexes:  A New and Efficient Route to β,γ-Unsaturated Thioesters

  摘要：

  The reaction of allylic alcohols with thiols and carbon monoxide in the presence of catalytic quantities of Pd(OAc)(2) (3 mol %), triphenylphosphine (12 mol %), and p-TsOH (5 mol %) leads to a novel thiocarbonylation to afford beta,gamma-unsaturated thioesters in good to excellent yields. Other palladium catalyst systems such as Pd-2(dba)(3). CHCl3-PPh3-p-TsOH, Pd(PPh3)(4)-p-TsOH, and Pd(OAc)(2)-dppb-p-TsOH are also effective for this transformation. The thiocarbonylation reaction is believed to proceed via a allylpalladium intermediate. The reaction occurs highly regioselectively at the least hindered allylic terminal carbon of the substrate to give the products. This new carbonylation procedure was readily applied to a variety of allylic alcohols and both aromatic and aliphatic thiols.

  CHCl(3)-PPh(3), Pd(PPh(3))(4), and Pd(OAc)(2)-dppp are also effective for this reaction. The thiocarbonylation reaction is believed to proceed via an allylpalladium intermediate. The reaction exhibits high regioselectivity, in which the thiophenyl group adds to the less substituted double bond of allenes to give beta,gamma-unsaturated thioesters.

  一系列的单取代和二取代的烯丙基用硫醇和一氧化碳进行直接硫羰基化反应，以73-94％的收率形成相应的β，γ-不饱和硫酯。该反应需要在100摄氏度的CO（400 psi）气氛下于THF中催化量的Pd（OAc）（2）（3 mol％）和三苯膦（12 mol％）在THF中的反应。其他钯催化剂体系如Pd（2）（dba）（3）.CHCl（3）-PPh（3），Pd（PPh（3））（4）和Pd（OAc）（2）-dppp也是对于该反应有效。据信硫羰基化反应是通过烯丙基钯中间体进行的。该反应表现出高的区域选择性，其中硫代苯基基团加到较少取代的丙二烯双键上，得到β，γ-不饱和硫代酯。

  Three-component coupling reaction of conjugated dienes, thiols, and carbon monoxide affords an atom-economical thiocarbonylation of the dienes to give beta,gamma-unsaturated thioesters as the sole products. A catalyst system based on [Pd(OAc)(2)] and Ph(3)P showed excellent catalytic activity. The thiocarbonylation was performed under an atmosphere of carbon monoxide (400 psi) at 110 degrees C in CH(2)Cl(2)

  共轭二烯，硫醇和一氧化碳的三组分偶联反应提供了二烯的原子经济的硫羰基化反应，从而以β，γ-不饱和硫代酯为唯一产物。基于[Pd（OAc）（2）]和Ph（3）P的催化剂体系显示出优异的催化活性。硫羰基化反应是在一氧化碳（400 psi）的气氛下，在CH（2）Cl（2）中于110摄氏度进行的，反应时间为60 h。从容易获得的起始原料合成了多种硫代酸酯，它们的产率高至优异。据信该反应通过eta（3）-烯丙基钯中间体进行。适用于多种共轭二烯的硫羰基化反应具有很高的区域选择性，后者取决于eta（3）-烯丙基铝配合物的空间特征和稳定性。
