Optically pure aminopolyols and polyoxamic acid derivatives from aziridine-2-carboxylates

Various new chiral building blocks could easily be prepared from optically pure cis and trans ethyl 3-(1′,3′-dioxolan-4′-yl)aziridine-2-carboxylates. A stereochemically pure 1,3-dioxolan in the allyl position of an α-bromoacrylate induced a high (3R*,4′S*

Novel synthesis of phytosphingosine from levoglucosenone

Phytosphingosine, (2S,3S,4R)-2-amino-1,3,4-octadecanetriol was prepared in 8.6percent overall yield in 17 steps from levoglucosenone (1,6-anhydro-3,4-dideoxy-β-D-glycero-hex-3-enopyranos-2-ulose) by reduction of the carbonyl group, selective cis-oxyamination on the carbon-carbon double bond, oxidation of the 2-mydroxyl group to the carbonyl group, regioselective Baeyer-Villiger oxidation, reduction of the afforded lactone to the linear amino alcohol, oxidation of the primary hydroxyl group to the aldehyde, introduction of the hydrocarbon chain using a Wittig reaction, hydrogenation of the resulting carbon-carbon-double bond, and deprotection. - Keywords: Phytosphingosine: 2-Amino-1,3,4-octadecanetriol: Levoglucosenone: cis-Oxyamination
