All right, so if you look at the diagram given in the book, you'll see that this molecule right here is that same diagram.
00:10
And given that the nh3 plus is on a wedge, it's in the s configuration.
00:15
So we can prepare this in a very similar way as the example, right? so it says to use a z amino acid.
00:24
So i'm going to basically just have something that looks like this, right? where i'll have my cobroxs group here, and what looks like a protected, a main group, that nh, c -a -c -o -3.
00:38
I'm sorry, c -o -c -h -3.
00:42
And this is the z configuration, so the two highest priorities should be on the same side of the double bond, which means i'm going to have an h here.
00:50
Now i pick, basically just kind of tack my r group onto this part.
00:55
So in this case, this whole thing is going to be the r group.
00:59
So i'm basically just going to draw that right here.
01:01
So i'm going to go one, two, three, four.
01:06
And if i count my carbons, they say it the same.
01:08
I've got one, two, three, four carbons here.
01:11
One, two, three, four carbons there...
