  Conventional and Microwave Assisted Hydrogenolysis Using Zinc and Ammonium Formate

  摘要：

  The selective deprotection of several N-Bzl amino derivatives to the corresponding amines and the removal of S-Bzl and O-Bzl groups from the protected amino acids with ammonium formate and commercial zinc dust are reported. Many other reducible or hydrogenolysable substituents such as halogens, methoxy, phenol, ester, acid, ethene, and Boc groups are unaffected.

  方便，通用地将酰胺还原为低价钛的胺

  摘要：

  AbstractLow‐valent titanium readily prepared in situ from TiCl4 and Mg powder in THF is found to be an active agent for the reduction of amides which were previously considered to be inert towards low‐valent titanium. The reaction proceeds under very mild conditions, and is applicable to all types of amides, primary, secondary and tertiary, to produce the corresponding amines in good to excellent yields. This new finding provides a practical, convenient and general method for the important transformation of amides to amines. A plausible reaction mechanism is proposed.magnified image

  selective non-noble metal-based catalysts for the chemoselective reduction of nitro compounds in aquo media under mild conditions is an attractive research area. Herein, the synthesis of subnanometric and stable cobalt nanoclusters, covered by N-doped carbon layers as core–shell (Co@NC-800), for the chemoselective reduction of nitroarenes is reported. The Co@NC-800 catalyst was prepared by the pyrolysis

  Gold standard support! The direct reductive mono‐ or di‐N‐alkylation of aromatic nitro compounds with alcohols, using a hydrogen‐borrowing strategy, was efficiently promoted by a ligand‐free titania‐supported gold catalyst system (see scheme). A variety of nitroarenes were selectively converted into the corresponding secondary or tertiary amines in good to excellent yields without any co‐catalysts

  C═C bond breaking to access the C═N bond remains an underdeveloped area. A new protocol for C═C bond cleavage of alkenes under nonoxidative conditions to produce imines via an iron-catalyzed nitrene transfer reaction of 4-hydroxystilbenes with aryl azides is reported. The success of various sequential one-pot reactions reveals that the good compatibility of this method makes it very attractive for

  An efficient use of NiCl2·6H2O, for the cross-coupling of arylboronic acids with various N-nucleophiles, has been demonstrated. The method is practical and offers an alternative to the corresponding Cu-mediated Chan–Lam process for the construction of the C–N bond.
