Abstract: The molecular structures of methyl (R)-3-{(1R,4S)-6-methoxy-4,7-dimethyl-5,8-bis[(triisopropylsilyl)oxy]-1,2,3,4-tetrahydronaphthalen-1-yl}butanoate and methyl (E)-3-{(1R,4S)-8-hydroxy-6-methoxy-4,7-dimethyl-5-[(triisopropylsilyl)oxy]-1,2,3,4-tetrahydronaphthalen-1-yl}acrylate exhibit the same configurations of the stereo centres in the 1,2,3,4-tetrahydronaphthalene moiety, the conformation of which is nearly identical in the two molecules. read more here.
