Abstract The eudesmanolides vulgarin and peroxyvulgarin were obtained via a biogenetic-type route that involved photo-oxygenation of 1-oxo-5αH,6,11βH-eudesm-3-en-6, 12-olide. The α-face singlet oxygen ( 1 O 2 ) attack resulted in the production of peroxyvulgarin as the major product. Stannous chloride reduction of that compound readily yielded vulgarin. These two compounds, vulgarin and peroxyvulgarin
