Student question 2013: "When doing an epoxide opening on a trans-decalin derivative, can the trans-diequatorial product form at all, or is it impossible (since ring-flipping a trans-decalin is impossible)?" Answer: The decalin system is locked, as for when you have one ring and a tert-butyl. So yes, no ring flipping of the products. So you will get very significant selectivity for trans-diaxial, which stays trans-diaxial.
