We've learned in class that epoxide ring openings can be catalyized with acids, and I seem to recall either the professor or a classmate mentioning that they also react with bases, but some quick internet searching didn't turn up anything useful. Do epoxide rings react with bases, and if so, what is the mechanism?
(Dis)claimer: this is just for my own curiosity/learning, and not being asked as a homework/test question (yet).
