This review systematically highlights the advances in the direct transformation of propargylic alcohols with sulphur-containing reagents for the construction of sulphur-containing compounds.
A Lewis acid-mediated, 5/6/7/8-endo-dig reductive hydroalkoxylation cascade on enynols gives expeditious, diastereoselective access to small and medium ring cyclic ethers with a long aliphatic side chain.
We describe a catalyst-free visible-light mediated akynylperfluoroalkylation of unactive alkenes with perfluoroalkyl iodides, which provides a series of α-perfluoroalkyl-β-alkynyl ketone derivatives.
Manipulating the structural differences in the reaction substrates leads to the formation of distinct products. Computational evidence that supported a π–π stacking assisted regioselectivity regulatory mechanism was presented.
Cycloisomerization of 7-en-2-ynone with an aluminum halide gives different cyclic products from those with BF3 as a homologous element halide.
