I want really to know this way.
I am reading a book on organic chemistry. and it explains..
to block an α-position, it uses ii, BuSH, TsOH. and
to remove the one, it uses KOH H2O ethylene glycol, reflux.
I can understand the blocking. but I could not understand the removing with KOH H2O ethylene glycol, reflux.
Could not you teach me the mechanism just on the removing, this?
