In this problem, we have a structure with an epoxide ring, so that's an oxygen that's bound to carpins to make a three -membered ring.
00:09
And then we have a greniered reagent here.
00:14
So with a greenered reagent, we're going to be able to form a new carbon -carbon bond.
00:20
And keep in mind, we can think of this as a separation of charges where a carbon is negatively charged, and magnesium is positively charged.
00:30
This acts as an anion, so it's going to attack our least substituted site of our apopside ring.
00:37
So that's going to be here, and that will break this bond and put those electrons on oxygen.
00:46
So here we'll have a negatively charged oxygen, and then on the next carbon, we have our methyl group, and now we're attached to, we have one carbon, and then that's attached to a benzene ring.
01:11
So we have this here...
