Herein, authors report on the photocatalytic reaction of acceptor/acceptor diazoalkanes with terminal alkynes. Exptl. and computational studies suggest the formation of a key triplet carbene intermediate that underwent an addition reaction to the alkyne followed by cyclization to give furan heterocycles (31 to 90% yield). This reaction was studied with a broad range of alkynes and acceptor/acceptor diazoalkanes and now provides access to furans under mild reaction conditions. In the experiment, the researchers used many compounds, for example, 3-Ethynylthiophene (cas: 67237-53-0COA of Formula: C6H4S).
3-Ethynylthiophene (cas: 67237-53-0) belongs to benzothiophene derivatives. Benzothiophene scaffolds are of great importance due to its increased presence in bioactive molecules. It has been used as a raw material for the synthesis of biologically active structures and is found in pharmaceuticals such as leukotriene synthesis inhibitors and antifungals, as well as in many natural products.COA of Formula: C6H4S
