This molecule has two, and our goal is to determine the configuration of each chirality center, so at the intersection of these lines here, we know that this is a chiral center and then we have another one down ...
WebConvert the Fischer projections into tetrahedral representations and assign R or S stereochemistry to each (4 marks). 3. A useful and general method for the synthesis of alcohols is the addition of Grignard reagents to carbonyl compounds.
