摘要:A New Development In The Chemistry Of Arenes Activated Toward S(N)Ar Reactions By The Cyclopentadienyliron (Fecp+) Moiety Is Presented In This Work. A Class Of Diiron Complexes Of Diphenoxybenzenes Was Prepared In A Highly Efficient And Very Mild Fashion. Dihydroxyaromatic Compounds Served As Dinucleophiles,Allowing For The Formation Of The Diiron Complexes. This Could Be Achieved In Either A One Or Two Step Procedure. A Wide Variety Of Dinucleophiles Were Incorporated Into This Study,As Well As A Number Of Fecp+ Activated Arenes. It Is Shown That These Reactions Are Not Inhibited By Bulky Substituents On Either The Dinucleophiles Or Activated Arenes. The Diiron Complexes Themselves Could Also Undergo S(N)Ar Reactions,Provided That The Complexed Arenes Contained A Chlorine Substituent. This Allowed For The Functionalization Of The Complexes With Species That Could Not Be Introduced Directly In Their Syntheses. The Carbon Nucleophiles Generated From Ethyl Cyanoacetate Or (Phenylsulfonyl)Acetonitrile Could Be Attached To The Complexed Ethers In This Manner. The Fecp+ Moieties Were Removed Easily By Photolytic Demetalation Which Allowed For The Recovery Of A Wide Range Of Functionalized Diphenoxybenzenes. This Methodology Is Advantageous Over All Those Previously Reported And Should Be A Practical Route To The Synthesis Of Aromatic Ethers.

摘要:The present invention provides methodology for carbon-nitrogen bond formation via vinyl or aryl amination. In the process of the invention, an sp 2 hybridized radical is reacted with an azomethine moiety to form pyrrolidine and indole compounds. The methodology provides a facile process for the synthesis of compounds having the pyrrolidine or indole subunit and is especially advantageous for compounds having acid or base labile functional groups and/or is comprised of chiral centers susceptible to acid/base epimerization.
