  The present invention relates to a process for producing an optically active 3-(4-hydroxyphenyl)propionic acid useful as intermediates for medicines, through short steps in good yield and with high optical purity. More specifically, the present invention relates to a process for producing an optically active 3-(4-hydroxyphenyl)propionic acid of the formula (6): wherein R 2 is an alkyl group; R 5 to R 8 are each independently a hydrogen atom or a substituent; and the symbol * is an chiral carbon atom, or a salt thereof, which comprises reacting a benzaldehyde of the formula (1): wherein R 1 is a protective group; and R 5 to R 8 are each the same as defined above, with a glycolic acid derivative of the formula (2): wherein R 3 is a hydrocarbon group; and R 2 is the same as defined above, hydrolyzing the resulting product to give a cinnamic acid of the formula (4): wherein R 1 , R 2 and R 5 to R 8 are each the same as defined above, or a salt thereof, and subjecting the resulting cinnamic acid (4) or a salt thereof to asymmetric hydrogenation to give an optically active phenylpropionic acid of the formula (5): wherein all the symbols are each the same as defined above, or a salt thereof, followed by deprotection.

• Synthesis and structure–activity relationship of botryllamides that block the ABCG2 multidrug transporter
  作者：Kentaro Takada、Nobutaka Imamura、Kirk R. Gustafson、Curtis J. Henrich

  日期：2010.2

  In previous work, botryllamides discovered from the marine ascidian Botryllus tyreus were characterized as selective inhibitors of the ABCG2 multidrug transporter. However, the structural basis for this activity could not be established. In this study, botryllamide F, the core botryllamide structure, and botryllamide G, the most potent botryllamide ABCG2 inhibitor, were synthesized along with a series of structural variants for evaluation of structure - activity relationships. The biological activity of synthetic botryllamide analogs implied that the 2-methoxy-p-coumaric acid portion, and the degree of double bond conjugation within this group, were critical for inhibition of ABCG2. However, variations in the substituents on the two aryl groups did not appear to significantly impact the potency or degree of inhibition. (C) 2010 Elsevier Ltd. All rights reserved.
