Synthesis of Multisubstituted Enamides via Pd-Catalyzed Chloroallylation of Ynamides
摘要:
An atom-economic approach to the regio- and stereoselective assembly of highly substituted enamides is described via the Pd-catalyzed chloroallylation of ynamides at room temperature, which offers a simple and practical alternative to the stereodefined multisubstituted enamides.
Iron-Catalyzed Amidation of Alkynyl Bromides: A Facile Route for the Preparation of Ynamides
摘要:
A facile route to obtain ynamides in high yields was described. The products were achieved through the iron-catalyzed C-N coupling reaction of amides with alkynyl bromides in the presence of 20 mol % of N,N'-dimethylethane-1,2-diamine (DMEDA).
