Abstract

Alternative synthetic methodology has been investigated for the preparation of 3-propyl-3,4,5,1 O-tetrahydronaphtho[ 2,3-c]pyran-1,5,10(1H)-trione (3) with the view to making it more generally applicable to the synthesis of precursors viz. (2) to the extended pigment xylindein (1). Indications are that the more highly oxygenated naphthalene systems react less favourably towards free radical alkylations and mild oxidation than the simpler cases.
