Abstract

The absolute stereochemistry of oceanapiside, an antifungal α, ω-bis-aminohydroxylipid with four stereogenic centers from the marine sponge Oceanapia phillipensis Dendy, 1895, has been obtained as 2 S, 3 R, 26 R, 27 R from development and application of a general CD method based on superposition of additive exciton couplings in perbenzoyl derivatives of bis-amino alcohols. The method allows simultaneous determination of the local relative ...
