Cook, Yang Liu, and Christian Wolf*Department of Chemistry, Georgetown University, Washington, DC 20057, United StatesS * Supporting InformationABSTRACT: The addition of ynamides to acyl chlorides and N-heterocycles activated in situ with ethyl chloroformate has been accomplished at space temperature applying copper iodide as catalyst.Formula of 170097-87-7 This economical and sensible carbon-carbon bond formation provides convenient access to several different 3-aminoynones from aliphatic and aromatic acyl chlorides in as much as 99 yield.PMID:33547868 The addition to pyridines and quinolines happens beneath just about identical situations and proceeds with good to high regioselectivity, making the corresponding 1,2-dihydro-N-heterocycles in up to 95 yield.he exceptional chemistry of ynamines has received continuous attention because of the huge synthetic potential of those remarkably versatile constructing blocks. In unique, Csubstituted ynamines exhibiting an internal triple bond have identified widespread use inside a range of reactions and in the total synthesis of natural compounds.1 The reaction scope of ynamines and derivatives thereof differs significantly from that of enamines and alkynes because the reactivity of the electronrich triple bond is dominated by the adjacent, strongly polarizing amine moiety. Mainly because ynamines are extremely reactive and as a result of restricted sensible use, ynamides that may be isolated and stored have come to be much more well-known in recent years. The growing availability of terminal ynamides, ynesulfonamides, and ynecarbamates based on practical procedures created by Witulski,two Bruckner,3 Saa,four and others has additional extended the common utility of ynamine chemistry, Figure 1.five Amongst essentially the most noteworthy reactionsTF.
