Chemie von ?-Aminonitrilen. Aziridin-2-carbonitril photochemische Bildung aus 2-Aminopropennitril
摘要:
AbstractThe English Footnotes (*) referring to Schemes 1‐6 are intended to provide an extension of this summary. In the Footnote (*) to Scheme 5, a definition of the term ‘chirogenic reaction step’ is given.2‐Aminopropenenitrile in solvents such as MeCN, MeOH, or H2O is photoisomerized by UV light to racemic aziridine‐2‐carbonitrile (rac‐2); the larger part of the starting material, however, fragments to HCN and MeCN. The observed photocyclization constitutes a structural connection within an ensemble of C3H4N2 compounds considered to be potentially relevant to prebiotic chemistry.
