a mild, efficient and fast method for the oxidation of alcohols and trimethylsilyl, tetrahydropyranyl and methoxymethyl ethers to their corresponding carbonyl compounds using cro3 in the presence of rice husk ash (rha) is reported. all reactions were performed at room temperature in high to excellent yields. a new, efficient and green catalyst, heterogeneous reaction conditions, easy work-up of...

a simple, mild and practical procedure has been developed for the synthesis of symmetrical and unsymmetrical ethers by using dmso, tbai in the presence of k2co3. we extended the utility of  potassium carbonate as an efficient base for the preparation of ethers. a wide range of alkyl aryl and dialkyl ethers are synthesized from treatment of aliphatic alcohols and phenols with various alkyl halid...

Thermal rearrangement of propargyl naphthyl ethers produced naphthopyrans. In the presence of sodium methoxide, propargyl naphthyl ethers were converted easily to naphthofurans and naphthodifurans in good yields

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...

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.

Pieces of the digestive gland of the starfish, Asterias forbesi, were incubated in vitro with various radioactive lipid precursors in order to follow the biosynthesis of the alkyl and alkenyl glycerol ethers. Acetate-1-14C was incorporated readily into alkyl glycerol ethers of both neutral lipid and phospholipid fractions, but very poorly into the alkenyl glycerol ethers. Stearic acid-l-14C and...

The allyl and propenyl ethers of diols and polyols have recently attracted increasing attention as monomers and comonomers [1–2]. Most convenient method of the preparation of propenyl ethers consists in isomerization of the corresponding, readily available allyl ethers. Moreover, this isomerization is a key step of deprotection of hydroxyl group, protected as allyl ether [3,4]. Particularly con...
