A Thieno-2H-chromene α-Amino Acid Derivative: Synthesis and Photochromic Properties
摘要:
[GRAPHICS]A new photochromic thieno-2H-chromene a-amino acid derivative was prepared by C-N palladium-catalyzed cross-coupling of a bromothieno-2H-chromene with the aminated aromatic side chain of the methyl ester of a N,N-diprotected amino acid. Its good photochromic properties demonstrated by flash photolysis and continuous irradiation indicate a possible application in ophthalmic lenses. It may also be inserted into peptides to give photoinduced reversible structural changes.
