Additive-Free Decarboxylative Coupling of Cinnamic Acid Derivatives in Water: Synthesis of Allyl Amines
摘要:
The first example of an additive-free decarboxylative coupling of cinnamic acid derivatives with formaldehyde and amines to afford the corresponding allyl amines is reported. This reaction is highly environmentally friendly because it was conducted in H2O and without any additives, releasing only CO2 and H2O as byproducts. This reaction showed a broad substrate scope including cyclic and acyclic amines and high functional group tolerance. Moreover, phenyl dienoic acid participated in this type of decarboxylative coupling reaction.

Amination of allylicalcohols is facilitated via cooperative catalysis. Catalytic Ti(O-i-Pr)4 is shown to dramatically increase the rate of nickel-catalyzed allylic amination, and mechanistic experiments confirm activation of the allylicalcohol by titanium. Aminations of primary and secondary allylicalcohols are demonstrated with a variety of amine nucleophiles. Diene-containing substrates also cyclize

Allylic amines were synthesized by a simple procedure using a biodegradable and easily recyclable heterogeneous cellulose–Pd catalyst through N-allylation of primary and secondary amines. The scope of this protocol includes aliphatic and benzylamines with substituted and unsubstituted allyl acetates and culminates in high yield syntheses. The highlights of the protocol include a ligand-free reaction

gold(I) catalyst in toluene at 80 °C gave the corresponding allylic amines in good to moderate yields. To the best of our knowledge, this is the first example for carrying out the gold-catalyzed -intermolecular hydroamination with an aliphatic amine.
在阳离子金 (I) 催化剂的存在下,在 80 °C 的甲苯中用吗啉处理丙二烯,以良好到中等的产率得到相应的烯丙胺。据我们所知,这是用脂肪胺进行金催化的分子间加氢胺化的第一个例子。
