Unformatted text preview: ny reaction you have learnt in OChem ­I. Show all the reagents you need and indicate stereochemistry where appropriate. If a racemic mixture is formed draw both enantiomers and write “racemic” next to the two structures. You can only move forward in the synthesis with the MAJOR product. A) ?? Br 2 /CCl4 2 moles NaNH 2 Br Br All carbon atoms should come from the same starting material. Use as many molecules of the starting material as you might need to get to the product B) ??? H2 Lindlar Catalyst HBr Br NaNH 2 H 2 /Pd Br 6 HW ­5 Dr. Shabbir 11/08/2013 Q6 ­These, are slightly more challenging synthesis questions. You need to show how the starting material can be converted in the product shown. You may use as many reactions as you need to make the desired product. Show all the reagents. Show all the molecules that you synthesize along the way pay close attention to regiochemistry and stereochemistry. If you make a racemic mixture show all products and make sure you label RACEMIC. You can only move forward in the synthesis with the MAJOR product. All carbon atom should come from the starting material OH OH ???
