PMB = p-methoxybenzyl =
DDQ =
Dichlorodicyanoquinone
Removal of p-methoxybenzyl protecting group
Removal of p-methoxybenzyl protecting group
IBX = 2-iodoxybenzoic acid =
IBX Mechanism
IBX is less soluble than the Dess-Martin Periodinane
EDCI = Ethyl(dimethylaminopropyl)carbodiimide
Carbodiimide Coupling Mechanism
