TL;DR: In this paper, the detection performance of free sugars and related compounds in plant tissues has been studied by use of a defined procedure involving cold ethanol extraction and conversion of the extracted saccharides to the peracetylated derivatives of aldononitriles, ketoximes, alditols, and nonreducing sugars.

TL;DR: The treatment of aldose derivatives that are protected at all but the anomeric hydroxy groups with N-dichloromethylene-N,N-dialkylammonium chlorides (alkyl = Me, Et) provides an improved method of preparing the corresponding glycosyl chlorides.
Abstract: The treatment of aldose derivatives that are protected at all but the anomeric hydroxy groups with N-dichloromethylene-N,N-dialkylammonium chlorides (alkyl = Me, Et) provides an improved method of preparing the corresponding glycosyl chlorides Analogous derivatives containing anunprotected C1-C2 diol give 2-O-(N,N-dialkylcarbamoyl)glycosyl chlorides

TL;DR: The reactivity of 5,6-anhydrogluco-furanose derivatives toward different cyanocuprates was examined in this paper, where the former epoxide led to the corresponding C-6 chainextended sugars.
Abstract: The reactivity of the 5,6-anhydroglucofuranose derivatives 1 and 3, readily prepared from D-glucose, toward different cyanocuprates was examined. The former epoxide led to the corresponding C-6 chainextended sugars, e.g., 2. Alkylation of 5,6-anhydro-3-deoxy-1,2-O-isopropylidene-α-D-erythro-hex-3-enofuranose 3 with mixed cyanocuprates RCu(CN)Li [R = Me, Bu] provided a convenient and stereospecific route to 3-C-alkyl (methyl, butyl)-3-deoxy-α-D-glucofuranose derivatives 12 and 14via 1,4-addition followed by hydroboration–oxidation.
