The structure below is known by its common name, riesling acetal. Two of the stereoisomers of this compounds have been isolated as one of the many compounds leading to the aroma of wines as they age. The (+)-(1S, 6R, *S)-riesling acetal has a woody, fruity, and flowery note while the ()-(1R, 6S, 8R)-riesling acetal has a slightly camphoraceous note. How many stereoisomers are possible for riesling acetal structure? O O...
