Simple preparation of ethyl 3-hydroxy-1,4-naphthoquinone-2-carboxylates 2 including heterocyclic analogs is accomplished by C-regioselective bis-acylation of aromatic and heteroaromatic β-keto esters 1.Compounds 2 are readily hydrolyzed and decarboxylated to the corresponding 2-hydroxy-1,4-naphthoquinone derivatives 3.

A series of novel 3-(1-benzotriazole)-nor-β-lapachones 5a–5l were synthesized as the NQO1-targeted anticancer agents. Most of these compounds displayed good antiproliferative activity against the breast cancer MCF-7, lung cancer A549 and hepatocellular ca

A selection of novel 2-hydroxy-3-nitro-1,4-naphthoquinones are shown to be potent inhibitors of rat passive cutaneous anaphylaxis (PCA) and to have highest potency with alkyl substitution at both C-6 and C-7. The most potent compounds were 7c and 7e which produced a 50% inhibition in the rat PCA test at doses of about 10 μM/kg following subcutaneous administration and showed activity after oral administration. Related 4-hydroxy-3-nitro-2(1H)-naphthalenones had no effect on rat PCA in doses up to 500 μM/kg.
