I didn't do TLC, I did NMR. There were two chiral centers, a mixture of R and S epoxides (I figured). I doubt any of it was glycol (when buffered with bicarbonate). Anethole epoxide rearranged very nicely to anethole ketone and the yields were excellent (both of the amination and rearrangement), and I'm sure isosafrole would do the same. I attempted it and got excellent yields of suspected mdp2p, however, I screwed up on the amination and got piss-poor yields (enough to celebrate news years eve... but not enough to post at the hive recommending this procedure to the general hive populace...)
