Ok, we have the following substrate and we're doing a series of reactions on this substrate.
00:13
First up is mcpba, that is a peroxy acid, right, it turns alkenes into epoxides.
00:24
Next we have a grignard reagent.
00:26
Ok, we follow that up with, sorry this is sort of a two -parter, so we're just counting this as 2a and 2b.
00:45
The first part of step two is the grignard reagent followed by acidic workup.
00:56
And finally we have a hydrogen gas with the catalyst palladium over carbon.
01:11
Ok, so what happens after the mcpba? recall that we get an epoxide.
01:23
So instead of a double bond between these carbons, we gain two bonds, two oxygen.
01:32
Ok, next we're going to install our grignard reagent and recall that in basic or we should say non -acidic conditions, our grignard reagent will always add to the less substituted carbon.
01:48
So i'm going to color code things here real quick.
01:51
Right, i'm going to say this carbon is red, i'm going to say this carbon is blue, and i'm going to color code our grignard reagent...
