Abstract
The structures of antibiotics SF2315A and B were determined to be [4aR-(4a.beta.,12b.beta.)] or [4aS-(4a.alpha.,12b.alpha.)]-4a,5,6,12b-tetrahydro-4a,8-dihydroxy-3-methylbenz[a]anthracen-1,7,12(4H)-trione and [1S-(1.beta.,4a.beta.,6a.beta.,12.beta.,12a.beta.,12b.beta.)] or [1R-(1.alpha.,4a.alpha.,6a.alpha.,12.alpha.,12a.alpha.,12b.alpha.)]-1,4,4a,5,6,6,6a,-12a,12b-octahydro-1,4a,8,12-tetrahydroxy-3-methyl-6a,12a-epoxybenz[a] anthracen-7(12H)-one, respectively from their spectroscopic analyses and single crystal X-ray diffraction analyses.This publication has 1 reference indexed in Scilit:
