Synthesis and photooxygenation of homochiral 2-methylpyrrole derivatives of chiral amino alcohols: simple, selective access to chiral bicyclic lactams
摘要:
Homochiral 2-methylpyrrole derivatives are synthesized in high yields starting from chiral amino alcohols and 5-chloro-3-pentene-2-one. The photooxygenation of these compounds in the presence of a photosynthesizer furnishes the pyrrolooxazolone structures in high diastereoselectivities. In all of the examples, trans-isomers are formed as the major products. (C) 2003 Elsevier Ltd. All rights reserved.
Conversion of homochiral amines, β-amino alcohols and α-amino acids to their chiral 2-methylpyrrole derivatives
摘要:
5-Chloro-3-penten-2-one reacts with the amino group of homochiral amines, amino alcohols, amino acid esters to form corresponding 2-pyrrole derivatives in good yield and without racemization. (C) 1997 Elsevier Science Ltd.
