Abstract:
The Diels-Alder reaction between 5-hydroxy-1,4-naphthoquinone and 5,5-dimethyl-3-vinyl-1,2-cyclohexadienyl acetate by endo addition gives the title compound, C(22)H(22)O(5), in 68% yield. This racemic diastereoisomer has the opposite regiochemistry to ochromycinone analogues produced previously and may allow access to a new type of anticancer-active saquayamycin analogue.
