Thank you! Don't worry I won't give out any info on anybody to other students.

Hi I'm a chemistry grad student. I joined this site because my TA and some of her lab mates joined and I wanted to check it out.

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
