Journal Article
Burroughs, L., Ritchie, J., Ngwenya, M., Khan, D., Lewis, W., & Woodward, S. (2015). Anionic sigmatropic-electrocyclic-Chugaev cascades: accessing 12-aryl-5-(methylthiocarbonylthio)tetracenes and a related anthra[2,3-b]thiophene. Beilstein Journal of Organic Chemistry, 11, https://doi.org/10.3762/bjoc.11.31

1,4-Diols resulting from the double addition of ArCCLi (Ar = Ph, substituted phenyl, 2-thienyl) to ortho-C6H4(CHO)2 undergo cascades to tetracenes on simple admixture of LiHDMS, CS2 and MeI. Acene formation proceeds by [3,3]-sigmatropic rearrangement...

1,4-addition of TMSCCl3to nitroalkenes: efficient reaction conditions and mechanistic understanding (2014)
Journal Article
Wu, N., Wahl, B., Woodward, S., & Lewis, W. (2014). 1,4-addition of TMSCCl3to nitroalkenes: efficient reaction conditions and mechanistic understanding. Chemistry - A European Journal, 20(25), https://doi.org/10.1002/chem.201402394

Improved synthetic conditions allow preparation of TMSCCl3 in good yield (70 %) and excellent purity. Compounds of the type NBu4X [X=Ph3SiF2 (TBAT), F (tetrabutylammonium fluoride, TBAF), OAc, Cl and Br] act as catalytic promoters for 1,4-additions t...
