Jose M Concellón et al.
Chemical Society reviews, 33(9), 599-609 (2004-12-14)
The development of methodologies for the formation of carbon-carbon double bonds could be considered one of the most important challenges in organic synthesis. To this end, beta-elimination reactions in 1,2-difunctionalised substrates have been one of the most important means of

Yakugaku zasshi : Journal of the Pharmaceutical Society of Japan, 120(3), 245-255 (2000-03-21)
This review deals with the rapid reduction of a variety of organic functionalities, including a new selective reduction of carboxylic acid, with samarium diiodide in the presence of additives under mild conditions. The single electron donor ability of samarium diiodide

Chemical Society reviews, 40(5), 2199-2210 (2011-01-19)
In this tutorial review we discuss recent advances in the field of ketyl-(het)arene cyclisations promoted by samarium diiodide and related processes. Couplings of samarium ketyls with carbon-carbon multiple bonds are perhaps the most useful reactions to create carbocycles and heterocycles

Organic letters, 17(1), 126-129 (2014-12-17)
A new synthetic route to clavilactone B, a naturally occurring inhibitor of epidermal growth factor receptor (EGFR) tyrosine kinase, is disclosed. The route features a sequential samarium-mediated radical cyclization-fragmentation of an indanone derivative, which provides rapid access to a 10-membered

Introduced by Henri Kagan more than three decades ago, samarium diiodide (SmI(2)) has found increasing application in chemical synthesis. This single-electron reducing agent has been particularly useful in C-C bond formations, including those found in total synthesis endeavors. This Review
