Notes: A ‘detailed’ mechanism should illustrate all intermediates, by-products, and electron-pushing arrows. The marking scheme is given for each question as a guide; It is subject to minor changes. In class, we learned how to synthesize epoxides from alkenes using meta-chloroperbenzoic acid (mCPBA). Epoxides, like bromonium ions and mercuronium ions, can be ring-opened with various nucleophiles. The stereochemistry of the product depends on if the ring-opening occurs under acidic or basic conditions. The following two reactions – ring opening of...

Can I somebody to write out a reaction mechanism for the following reaction series? 5-methyl-4-bromo-trans-2-hexene is subjected to MCPBA, then that epoxide product is opened under basic conditions, and finally the new product with an alcohol is oxidized using Pyridinium Dichromate. Thank you.

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:...
