Light-induced O-glycosylation of unprotected deoxythioglycosyl donors.
نویسندگان
چکیده
The O-glycosylation of several unprotected deoxythioglycosides and alcohols using 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) under long-wavelength UV irradiation was effectively realized using a single electron transfer (SET) mechanism. In some cases, the use of p-methoxyboronic acid was very effective in temporary protection of the 1,3-diol (C4 and C6 positions) of the unprotected glycosyl donors to increase the yields of the obtained O-glycosides.

Glycosylation in room temperature ionic liquid using unprotected and unactivated donors.
Glycosylation in room temperature ionic liquid is demonstrated using unprotected and unactivated donors. Modest yields of simple benzyl glycosides and disaccharides of glucose, mannose and N-acetylgalactosamine were obtained in 1-ethyl-3-methylimidazolium benzoate with Amberlite IR-120 (H(+)) resin or p-toluenesulfonic acid as promoters.
متن کامل1,2-cis Alkyl glycosides: straightforward glycosylation from unprotected 1-thioglycosyl donors.
A 1,2-cis-alkyl glycosidation protocol that makes use of unprotected phenyl 1-thioglycosyl donors is reported. Glycosylation of various functionalized alcohols was accomplished in moderate to high yield and selectivity to give the 1,2-cis-glycosides. In order to quickly develop optimum glycosylation conditions, an FIA (flow injection analysis)-ESI-TOF-MS method was developed that enabled rapid ...
متن کاملFirst o-glycosylation from unprotected 1-thioimidoyl hexofuranosides assisted by divalent cations.
The preparation of O-hexofuranosides was accomplished from unprotected 1-thioimidoyl furanosides as donors. The present methodology was first used for the synthesis of octyl galactofuranoside and further extended to D-galactofuranose-containing disaccharides. Within this study, we emphasized the need for additional complexing cations to maintain the furanose ring in its initial size. After expe...
متن کاملSynthesis of saponins using partially protected glycosyl donors.
[reaction: see text] A new class of glycosyl donors having unprotected 2- and 2,4-hydroxyl groups were investigated under the standard glycosylation conditions. This approach was shown to be generally effective for the synthesis of alkyl and steroidal glycosides. A natural saponin, containing 2,4-branched oligosaccharide, was prepared in 35% overall yield in four straightforward sequential reac...
متن کاملO-Benzoxazolyl imidates as versatile glycosyl donors for chemical glycosylation.
Herein, we report a new class of glycosyl donors, benzoxazolyl imidates, for chemical glycosylation. The O-benzoxazolyl (OBox) leaving group was designed with an aim to compare the relative reactivity and stability of similarly structured S-benzoxazolyl (SBox) glycosides (thioimidates) developed in our lab and glycosyl trichloroacetimidates (TCAI, O-imidates) developed by Schmidt. Novel OBox do...
