Synthesis of enantiomerically pure enones (2-benzyloxypyran-3-ones) derived from pentoses
(Elsevier, 2019-05)
The useful synthons sugar enones (2-benzyloxypyran-3-ones) derived from pentoses have been prepared starting from 2-acetoxyglycals or benzyl pentopyranosides. The glycals were glycosylated with benzyl alcohol in the presence ...
Phenylethylpyranone and aristolochic acid derivatives from Aristolochia urupaensis
(2017-11-01)
A new pyranone, (S)-2-(4-hydroxyphenylethyl)-6-methyl-2,3-dihydro-4H-pyran-4-one, with unusual carbon skeleton, and three new aristolochic acid derivatives (7-O-methylaristolochic acid F, sodium 7-O-methylaristolochate F ...
Stereospecific Synthesis of Pyrrolidines with Varied Configurations via 1,3-Dipolar Cycloadditions to Sugar-Derived Enones
(American Chemical Society, 2014-05)
Enantiomerically pure pyrrolidines have been obtained by 1,3-dipolar cycloaddition of stabilized azomethine ylides and sugar enones (dihydropyranones) derived from pentoses. Thus, the S-enone (menthyl 3,4-dideoxy-(1S)-pe ...
