Appropriate N-ylides convert 2-methyl-1,4-naphthoquinone into 3-(acylmethyl) derivatives which can be cyclised to naphtho[2,3-c]pyran-5,10-diones by treatment with bromine and dehydrobromination with triethylamine; these diones give a variety of striking colours in acid media.
1H-Naphtho[2,3-c]pyran-5,10-dione derivatives, including a natural product (pentalongin), were generally synthesized in one-pot using a tandem conjugate addition-cyclization sequence between 2-(1-hydroxyalkyl)-1,4-naphthoquinones and enamines (or imines). The utility of this method was demonstrated in the synthesis of pyranonaphthoquinone antibiotics, (+/-)-eleutherin and (+/-)-isoeleutherin. (C) 1998 Elsevier Science Ltd. All rights reserved.
