摘要：

An attempt to synthesize APHE-3 (3-methylpyrazolo[1,5-b]isoquinolin-9(1H)-one 3) gave the tautomer 3-methylpyrazolol[1,5-b]isoquinoiin-9(4H)-one (9) instead, and led to a reconsideration of the structures assigned to the APHEs. The structures of the APHEs have now been reformulated as 15-18, known natural products, whose spectra are in close agreement with those reported for the APHEs. (C) 1999 Elsevier Science Ltd.
