Chemistry, like all the natural sciences, Application In Synthesis of H-SER-ILE-LYS-VAL-ALA-VAL-OH, begins with the direct observation of nature— in this case, of matter.146439-94-3, Name is H-SER-ILE-LYS-VAL-ALA-VAL-OH, SMILES is O=C(O)[C@H](C(C)C)NC([C@H](C)NC([C@H](C(C)C)NC([C@H](CCCCN)NC([C@H]([C@@H](C)CC)NC([C@@H](N)CO)=O)=O)=O)=O)=O, belongs to chiral-catalyst compound. In a document, author is Uraguchi, Daisuke, introduce the new discover.

The development of a photoinduced, highly diastereo- and enantioselective [3 + 2]-cycloaddition of N-cyclopropylurea with alpha-alkylstyrenes is reported. This asymmetric radical cycloaddition relies on the strategic placement of urea on cyclopropylamine as a redox-active directing group (DG) with anion-binding ability and the use of an ion pair, comprising an iridium polypyridyl complex and a weakly coordinating chiral borate ion, as a photocatalyst. The structure of the anion component of the catalyst governs reactivity, and pertinent structural modification of the borate ion enables high levels of catalytic activity and stereocontrol. This system tolerates a range of alpha-allcylstyrenes and hence offers rapid access to various aminocyclopentanes with contiguous tertiary and quaternary stereocenters, as the urea DG is readily removable.
