An efficient and catalytic protocol for highly stereoselective construction of β-mannopyranosylation has been developed. Glycosylation of 2,6-lactone-bridged mannopyranosyl ortho-hexynylbenzoate with various acceptors proceeded smoothly in the presence of 5% Hg(II) at room temperature, resulting in the corresponding β-mannosides in high yield and exclusive β-stereoselectivity. In the experiment, the researchers used many compounds, for example, (1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5Product Details of 2216-51-5).
(1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Product Details of 2216-51-5
