Patman 2 CH 310/318M Sp.2011 Reactions Thus Far. . . Predict the products, only show one isomer with relevant stereochemistry and label racemic or meso when appropriate. V. Patman 3 CH 310/318M Sp.2011 Thurs 4.07.11 Stereochemistry of Products We have seen two examples in which reaction of achiral starting materials gives chiral products. In each case, the product is formed as: a racemic mixture a meso compound Two important points about the creation of chiral molecules. Optically active (enantiomerically pure) products can never be produced from achiral starting materials and achiral reagents under achiral...
