  High regioselectivity in electrochemical α-methoxylation of N-protected cyclic amines

  摘要：

  N-Protecting groups of alpha-substituted cyclic amines strongly affected the regioselectivity in electrochemical methoxylation of these compounds. Namely, N-acyl derivatives were transformed into alpha'-methoxylated compounds, while N-cyano derivatives changed into alpha-methoxylated derivatives. Furthermore, Lewis acid catalyzed nucleophilic substitution of the alpha-methoxylated compounds protected with cyano group afforded alpha,alpha-disubstituted cyclic amines. (c) 2008 Elsevier Ltd.

• Direct electrochemical α-cyanation of N-protected cyclic amines
  作者：Samuel Shikuku Libendi、Yosuke Demizu、Osamu Onomura

  DOI：10.1039/b816598j

  日期：——

  α-Cyanation of N-protected cyclic amines was achieved using a direct electrochemical method. Unsubstituted N-protected cyclic amines were easily cyanated at the α-position using an undivided cell in high yields; moreover, α-cyanation of α′-substituted pyrrolidine and α′-,β′- or γ-substituted piperidines smoothly proceeded in high yield and with high to excellent diastereoselectivity. α-Substituted N-cyano-pyrrolidines and -piperidines were also cyanated at the more substituted position (the α-position) using a divided cell with high yield and high regioselectivity.

  通过直接电化学方法，实现了N-保护的环状胺的α-氰化。未取代的N-保护环状胺在无隔膜电池中易于在α位进行氰化，产率很高；此外，α'-取代的吡咯烷和α'、β'或γ-取代的哌啶也能顺利进行高产率的α-氰化，并具有高度至优异的非对映选择性。α-取代的N-氰基吡咯烷和哌啶在有隔膜电池中也能在更取代的位置（α位）进行氰化，产率高且具有高区域选择性。
