In the chemistry of polyfunctionalized organic compounds, protecting groups that can undergo mild and selective cleavage while still being stable during the entire synthetic sequence are often required. In this work, we present a straightforward conversion of the robust p-chlorobenzyl ether into the more labile and well-described p-methoxybenzyl ether using palladium catalysis. This reaction was demonstrated to be high yielding and compatible with a wide range of functionalities, thereby providing a useful supplement to the conventional ether protecting groups.

Salidroside is a phenylpropanoid glycoside isolated from Rhodiola rosea L., a traditional Chinese medicinal plant, and has displayed a broad spectrum of pharmacological properties. In this paper, about 18 novel salidroside analogues were prepared through Koenigs-Knorr method, the effects of these compounds over PC12 was assessed with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method. The novel compounds differ in the substituents attached to the benzene ring or in the glycosyl donor. According to the data, compounds (3,5-dimethoxyphenyl)methyl β-D-glucopyranoside and (3,5-dimethoxyphenyl) methyl β-D-galactopyranoside with methoxy group at 3 and 5-positions of the benzene ring were the most viability at concentration of 300 μmol/l and 60 μmol/l, respectively.
