Predicting the major product
« on: November 27, 2014, 05:44:17 PM »
Hi all,

Unfortunately organic chemistry isn't my strong point (love inorganic and physical) I always struggle with it.. Due to a bereavement I have slipped behind and I don't even know where to begin on this question? Can any one give me any advice? Help? Anything? Thank you in advance

Do you know what class of compound the second reagent is?  If you know the general class, do you know, or can you look up online and in a textbook, what reactions it undergoes?  These are good ways to start, when you've fallen behind.

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Another aspect of the indicated reaction should be considered: Note that the first compound contains a chiral center (only the S-enantiomer is shown).

Thus, after you have decided the manner in which the second compound reacts with the first, the question of reaction diastereoselectivity with concomitant asymmetric induction that accompanies erythro vs. threo product formation should be considered.

The following reference may prove helpful: http://en.wikipedia.org/wiki/Asymmetric_induction

So what is the stereochemistry of your new alcohol?
