Syntheses in enantiopure form of four diastereoisomeric naphthopyranquinones derived from aphid insect pigments

The first syntheses are described of the four enantiopure naphthopyranquinones (1R,3R,4S)- and (1R,3R,4R)-3,4-dihydro-4,7,9-trihydroxy-1, 3-dimethylnaphtho[2,3-c]pyranquinone (quinone A 1 and quinone A' 2) and their two C-3 epimers, the (1R,3S,4S)- and (1

Asymmetric diastereoselective syntheses of the aphid insect pigment derivatives quinone A and quinone A′

Commercially available (R)-lactate has been used to provide the chiral source for the asymmetric diastereoselective syntheses of all four stereoisomers of 3,4-dihydro-4,7,9-trihydroxy-1,3-dimethylnaphtho[2,3-c]pyran-5,10-quinone based on 3R stereochemistr
