Unformatted text preview: Look at the structure of lovastatin, and determine the total number of stereoisomers possible for this molecule. Write your answer in the appropriate box. Several (but not all) of the chiral centers in lovastatin are marked with arrows. In the box associated with each arrow, indicate the stereochemical configuration of the chiral center as ( R ) or ( S ) . Total number of stereoisomers possible = O O H O HO O * * * * * * * * 256 = 2 8 (The 8 chiral centers are marked in the structure below) 1 2 3 4 ( S ) 1 2 3 4 ( R ) 1 2 3 4 ( R ) 1 2 3 4 ( R )...
