Stereocontrolled elaboration of natural (-)-polycavernoside A, a powerfully toxic metabolite of the red alga Polycavernosa tsudai

A stereoselective total synthesis of natural levorotatory polycavernoside A (1) has been achieved. Initial investigations produced the properly activated disaccharide unit 18b via the conjoining of building blocks originating from L-fucose and D-xylose. T
