2019年1月21日 · Step-3, Can I use MCPBA to convert an alkene containing an alcohol group to its corresponding epoxide? I'm worried that MCPBA can protonate the alcohol to generate the carbocation (moreover, the allylic carbocation makes it even more probable!) and that will lead to byproducts. That's all. Any help will be appreciated.

MCPBA ( meta-Chloroperbenzoic acid) is a peracid which can react with aldehyde or ketone to undergo ...

2017年10月28日 · $\begingroup$ Since step 2 occurs after step 1, epoxidation only occurs after the protection of the OH group. By implication, enolization must have occured before step 2 ( I suspect enolization catalyzed by NEt3).

The mechanism of the epoxidation of an alkene by mCPBA is a concerted process. However, there is still a correct order in which to draw the curved mechanistic arrows of this reaction, as drawing them in the wrong order will ( like most mechanisms ) likely lead to a significant error

To approach the first step of solving this reaction sequence, convert the alkene to an epoxide using mCPBA in . Step 1 The question is about drawing the products of the two-step reaction sequence.
