Okay, so we're asking the products with following reactions, and we're starting with the first one we have an alpha -beta unsaturated ketone.
00:16
This is reacting with a gilman reagent.
00:30
So the gilman reage is not strong enough to attack the carbonyl carbon.
00:34
It's going to attack the beta carbon, and we'll add one equivalent of methyl as opposed to.
00:49
Okay, for b, we have the same structure, and this is reacting with methyl -minesium bromide in h -3 plus.
01:11
So the green yard ridge is going to attack the carbon -no -carbon, and h -ther plus will give us the alcohol.
01:33
So we have a chiral center here too.
01:35
If we put the oh in the front, this is going to be one.
01:52
This has to be two, because we're comparing this carbon and this.
01:59
This is three, and this is four.
02:02
So it's going, this is going to be r, and then s would be the opposite corality.
02:27
Okay, for c.
02:29
We have a benzene ring with a 3 -carbon ketone...
