Asymmetric synthesis of 3(S),17-dihydroxytanshinone
摘要:
The first synthesis of 3(S),17-dihydroxytanshinone was achieved by ultrasound promoted Diels-Alder reaction of the protected 3-hydroxymethyl-4,5-benzofurandione with a vinylcyclohexene derivative. Bioassay showed that the synthetic 3(S), 17-dihydroxytanshinone was active in vitro against HL-60 tumor cell line by MTT method. (C) 2003 Elsevier Ltd. All rights reserved.
