Hi everyone I have two questions.
1. How can I predict the stereochemistry of the reaction of (S)2-methoxy-®4-methoxy-3-hexanone with tetramethyl ammonium triacetoxy borohydride. What face will it attack from? 2. The reaction of 3(S)-hydroxy-4(S)-isopropylcyclohexanone with sodium triacetoxy borohydride. What will be the stereocenter of the aclohol? What face will it attack from in this case? I heard my TA joined this forum and I would like to get an answer from her or someone in her group that took the class from the same prof before. He is on my comps committee and I need an answer to these questions to finish my molecule.
Cheers
