, (2021/10/27)
A synthesis method of a release type xylose ester spice for flavoring tobacco is provided. The glucose is used as a raw material, the principle of esterifying carboxylic acid and alcohol to prepare ester is adopted, a common parent carboxylic acid which c

An approach for efficient synthesis of C-glycosyl amino acids is described. Different from typical photoredox-catalyzed reactions of imines, the new process follows a pathway in which α-imino esters serve as electrophiles in chemoselective addition reactions with nucleophilic glycosyl radicals. The process is highlighted by the mild nature of the reaction conditions, the highly stereoselectivity attending C-C bond formation, and its applicability to C-glycosylations using both armed and disarmed pentose and hexose derivatives.

A well-stabilized method for synthesis of N-acylbenzotriazoles from carboxylic acids using I2/PPh3 in anhydrous dichloromethane has been extended in glycochemistry to synthesize glycoconjugated N-acylbenzotriazoles with high yields at room temperature in 2-hour reaction time.

, p. 9179 - 9187 (2008/02/10)
Diastereoselective synthesis of spiro-β-lactams via [2+2] cycloaddition reaction of imines and chiral ketenes is described. The chiral ketene was prepared from commercially available, inexpensive d-glucose. Although, theoretically four diastereomers are p
Short Synthetic Route to Congeners of the Undecose Antibiotic Herbicidin
Bearder, John R.,Dewis, Mark L.,Whiting, Donald A.
, p. 227 - 234 (2007/10/02)
The undecose backbone of the herbicidins has been assemled via direct alkylation, hydroxyalkylation, or acylation of the cyclic vinylanion 5 with the xylofuranose triflate 14, aldehyde 6, or acid chloride 10, respectively.
Peparation of higher-carbon sugars by stereoselective osmylation of related allylic alcohols
Jarosz, Slawomir

The catalytic osmylation of the following higher-carbon sugar allylic alcohols and enones was examined. 3-O-Benzyl-5-deoxy-5-C--1,2-O-isopropylidene-α-D-xylofuranose (5) af
New Chirons from D-Glucose. Regio- and Diastereoselective C-C Bond Forming Reactions Exploiting Novel Aldotetrafuranose Acetates as Chiral Synthetic Equivalents of Tartaric Aldehydes

, p. 4100 - 4105 (2007/10/02)
Two differentially protected tetrafuranose acetates 5 and 6 have been prepared from diacetone D-glucose in parallel short routes.They clearly act as chiral synthetic equivalents of D- and meso-tartaric aldehydes when exploited in Lewis acid promoted react
NOVEL SYNTHETIC EQUIVALENTS OF DIFFERENTIALLY PROTECTED TARTARIC ALDEHYDES. A SIMPLE ROUTE TO USEFUL C-4 CHIRAL SYNTHONS.
Dhavale, Dilip D.,Tagliavini, Emilio,Trombini, Claudio,Umani-Ronchi, Achille
, p. 6163 - 6166 (2007/10/02)
The synthesis of 4-acetoxy-3-O-benzyl-1,2-O-isopropylidene aldotetroses from D-glucose is reported.These synthetic equivalents of tartaric aldehydes are chemoselectively reduced at the acetoxylated center leading to a series of useful differentially protected C-4 chiral synthons.
