Oxidative photoredox catalysis: mild and selective deprotection of PMB ethers mediated by visible light.
Herein we report an advancement in the application of visible light photoredox catalysts in the oxidation of electron-rich arenes resulting in the selective deprotection of para-methoxybenzyl (PMB) ethers. This method is highlighted by excellent functional group tolerance, protecting group orthogonality, mild reaction conditions and avoidance of stoichiometric redox byproducts.
متن کاملBoronic esters as protective groups in carbohydrate chemistry: processes for acylation, silylation and alkylation of glycoside-derived boronates.
Procedures for selective installation of acyl, silyl ether and para-methoxybenzyl (PMB) ether groups to glycoside substrates have been developed, employing phenylboronic esters as protected intermediates. The sequence of boronic ester formation, functionalization and deprotection can be accomplished with only a single purification step, and the boronic acid component can be recovered and reused...
متن کاملChemoselective deprotection of triethylsilyl ethers.
An efficient and selective method was developed for the deprotection of triethylsilyl (TES) ethers using formic acid in methanol (5-10%) or in methylene chloride 2-5%) with excellent yields. TES ethers are selectively deprotected to the corresponding alcohols in high yields using formic acid in methanol under mild reaction conditions. Other hydroxyl protecting groups like t-butyldimethylsilyl (...
متن کاملA mild and efficient method for the selective deprotection of silyl ethers using KF in the presence of tetraethylene glycol.
A mild and efficient protocol for the deprotection of silyl ethers using KF in tetraethylene glycol is reported. A wide range of alcoholic silyl ethers can be selectively cleaved in high yield in the presence of certain acid- and base-labile functional groups. Moreover, the phenolic silyl ethers were cleaved exclusively, without affecting the alcoholic silyl ethers, at room temperature.
متن کاملAmmonium Decatungstocerate(IV): An Efficient Catalyst for the Protection and Deprotection of Tetrahydropyranyl Ethers
In multi-step organic syntheses, the protection and deprotection of tetrahydropyranyl (THP) ethers is one of the most frequently used methods. Over the years, different methods have been used from various catalytic systems for the protection of hydroxyl groups as THP ethers and their deprotection. Herein we have reported that various alcohols and phenols have been efficiently converted to the c...
