Angewandte Chemie - International Edition, 57(22), 6558-6562. doi:10.1002/anie.201803162 | Series/Report no.: | Angewandte Chemie - International Edition | Abstract: | Cobalt–diphosphine catalysts have been found to promote intramolecular reactions between a vinylcyclopropane and an alkyne to selectively afford either the [5+2] cycloaddition product or the homo‐ene reaction product under solvent control. The former product is exclusively formed in noncoordinating 1,2‐dichloroethane, whereas the latter is dominant in coordinating solvents, such as acetonitrile and dimethylacetamide. Furthermore, a highly enantioselective variant of the homo‐ene reaction afforded chiral tetrahydrofuran, pyrrolidine, and cyclopentane derivatives bearing 1,3‐diene and alkylidene substituents. | URI: | https://hdl.handle.net/10356/105752 http://hdl.handle.net/10220/48731 |
