I noticed on Chad's OChem reaction sheet for Electrophilic Addition Reactions...it says the Epoxidation reaction results in only 1 product...with anti stereoselectivity. This cannot be correct. It should result in only 1 product with SYN stereoselectivity, right? I'm guessing it was a typo, but can someone clarify?
I mean...the product (not an intermediate) contains a 3-membered ring with an Oxygen. There is no physical way that it can be Anti, since this is a 1 step reaction...that does the "Butterfly Mechanism." (it's on wikipedia, but basically the peracid and the alkene make a epoxide in 1 single step).
So...should the stereoselectivity be Syn or Anti?
