摘要
One-step treatment of daunomycinone with excess 2-aminoethanethiol and 2-aminoethanol in trifluoroacetic acid afforded at C-7 the thioether (77% yield) and ether (30% after recycling), respectively. Stereoselectivity for the natural IS over the 1R configuration was greater for the ether (97:3) than for the thioether (2.5:1). Esterification of daunomycin at C-7 with β-alanine was accomplished through the mixed anhydride of Z(OMe)-β-alanine. Preliminary biological tests suggest that the antitumor and DNA interactive properties of the anthracyclines can be retained in such structures. © 1979, American Chemical Society.
