Page - 3 - of 9 ЗА) To get an anti - 1, 2 diol configuration, you have to go through an epoxide ring-opening reaction. In class, we showed this reaction happening in acidic or in basic conditions with a different mechanism. Below, DRAW a good arrow-pushing mechanism, showing all steps, for the epoxide ring- opening under both conditions, separately. Of course, the same two (2) products form in either mechanism below. Mechanism: OH-/H2O H2O + mil H-O O Mechanism:...
