Synthesis and Absolute Configuration of Zonarol. A Fungitoxic Hydroquinone from the Brown Seaweed Dictyoptfris Zonarioides(1)
摘要:
AbstractA total synthesis of both the enantiomers of zonarol 1 was accomplished. Measurements of the ORD‐CD spectra of two bicyclic intermediates coupled with direct comparison of the natural and synthetic zonarol 1 established the absolute configuration of the naturally occurring (+)‐zonarol 1 as 1R, 4aR, 8aR.
