One of the simplest ways to establish an enantiomerically-pure ternary center is to selectively hydrogenate a trisubstituted alkene. While there are many examples of the enantioselective reduction of more highly…
Direct conversion of an unactivated C-H bond to a C-O, C-N or C-C bond is a powerful way to add valuable complexity to a substrate. While this is by no…
While alkene metathesis has become part of the toolkit of organic synthesis, investigators around the world are pushing the limits of the method as they employ the reaction in total…
Several creative new approaches to carbocyclic ring construction using transition metals have recently been reported. Dichlorocyclopropanes such as 1 are easily prepared by the addition of dichlorocarbene to the corresponding…
A recent publication by G. Barbarella and co-workers from Bologna, Italy (J. Org. Chem. 2004, 69, 4821.DOI: 10.1021/jo035723q)reports the rapid preparation of poorly soluble unsubstituted and modified α-quinque and sexithiophenes…
