Abstract

Stereoselective synthesis of 1, one of biologically active naphthoquinones from a Brazilian traditional medicine Tabebuia avellanedae, was achieved by utilizing Noyori reduction as a key step. Compound 1 displayed potent cytotoxicity against several human tumor cell lines, whereas it showed lower cytotoxicity against some human normal cell lines compared with that of mitomycin. On the Other hand, its enantiomer was less active toward the tumor cell lines than 1.
