Spontaneous absolute asymmetric synthesis

Spontaneous absolute asymmetric synthesis is a chemical phenomenon that stochastically generates chirality based on autocatalysis and small fluctuations in the ratio of enantiomers present in a racemic mixture.Tsuneomi Kawasaki, Kenta Suzuki, Masako Shimizu, Keisuke Ishikawa and Kenso Soai, Chirality, Volume 18, Issue 7, pages 479–482, 2006, {{doi|10.1002/chir.20273}} In certain reactions which initially do not contain chiral information, stochastically distributed enantiomeric excess can be observed. The phenomenon is different from chiral amplification, where enantiomeric excess is present from the beginning and not stochastically distributed. Hence, when the experiment is repeated many times, the average enantiomeric excess approaches 0%.Kenta Suzuki, Kunihiko Hatase, Daisuke Nishiyama, Tsuneomi Kawasaki, Kenso Soai, Journal of Systems Chemistry 2010, 1:5 (18 August 2010), {{doi|10.1186/1759-2208-1-5}} The phenomenon has important implications concerning the origin of homochirality in nature.{{cite journal | journal= Highlights in Chemical Science |year= 2008 |issue= 5 | url= http://www.rsc.org/Publishing/ChemScience/Volume/2008/05/Kenso_Soai_interview.asp | archive-url= https://web.archive.org/web/20160326010333/http://www.rsc.org/Publishing/ChemScience/Volume/2008/05/Kenso_Soai_interview.asp | url-status= dead | archive-date= March 26, 2016 |title= Interview: In the beginning... |accessdate=June 18, 2014 }}
