Abstract
Plumbagin (5-hydroxy-2-methyl-1,4-naphthoquinone) has been shown to have a potent insect ecdysis inhibitory activity. To test the activity of synthetic analogs, the synthesis of 2-alkyl-1,4-naphthoquinones via an ortho-directive metalation using naphthol methoxymethyl ether as a directive group was carried out. This method is also applicable to the synthesis of naphthoquinones having unsaturated side-chain.Keywords
