5-methoxy-1H-naphtho[2,1,8-mna]xanthen-1-one (1) and 5-methoxy-3H-naphtho[2,1,8-mna]xanthen-3-one (musafluorone 2), a pair of positional isomers isolated from Wachendorfia thyrsiflora and Musa acuminata, were synthesized in six steps in an overall yield of 53 % and 59 % starting from the corresponding methoxyphenalenones and employing an acid mediated cyclocondensation strategy. Preliminary assays
