The silver nitrate promoted reaction of propargyl bromide with (Z)-4-amino-3-penten-2-ones and (Z)-3-amino-2-butenoates provides rapid access to β-(Z)-[(1-propynyl)amino]enones and β-[(Z)-(1-propynyl)amino]enoates respectively.

The first heterogeneous gold(I)-catalyzed regiospecific hydroamination of ynamides and propiolic acid derivatives with anilines has been achieved by using a diphenylphosphine-functionalized MCM-41-supported gold (I) complex and AgNTf2 as catalysts under mild conditions, yielding the corresponding (E)-N-arylimines and (Z)-enamines in good to excellent yields with broad substrate scope. The new heterogeneous gold(I) complex can easily be prepared via a two-step procedure from commercially available reagents and recovered by simple filtration of the reaction mixture. The recovered catalyst (Ph2P-MCM-41-AuNTf2) can be reused at least seven times without addition of AgNTf2 as a co-catalyst and its catalytic efficiency remains unaltered. (Figure presented.).
Synthesis of Quinoxaline Derivatives via Tandem Oxidative Azidation/Cyclization Reaction of N -Arylenamines

A new method was developed for the synthesis of quinoxalines. This method employs N-arylenamines and TMSN3 as the starting materials and implements two oxidative C-N bond-forming processes in a tandem pattern by using (diacetoxyiodo)benzene as the common oxidant. The present reaction conditions are mild and simple and thus are useful in practical synthesis. (Chemical Equation Presented).
