(-)-(3S)-4-(2-{[4,4-Dimethoxy-6-(benzyloxymethyl)perhydropyran-2-yl]methyl}-1,3-dithian-2-yl)-4-methyl-3-(1,1,2,2-tetramethyl-1-silapropoxy)pentan-1-ol.
The absolute configuration was determined for the title compound, (-)-C(32)H(56)O(6)S(2)Si, (I), which was prepared in a synthetic study on the natural products bryostatins. Two independent molecules show similar conformations, except for the orientation of the methoxy groups.
