Asymmetric synthesis of 1,3-dithiolane nucleoside analogues

, p. 346 - 350 (2003)
We report the ready asymmetric synthesis of nucleoside analogues containing a 1,3-dithiolane ring that mimics the sugar moiety of natural nucleosides. The synthesis is accomplished in three main steps from benzoyloxyethanal 1,3-dithiolane, the key step being its conversion into a chiral monosulfoxide by a modified Sharpless sulfo-oxygenation reaction. The nucleoside analogues were obtained in good overall yields and with excellent enantiomeric excesses. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.

O-glycolaldehydes (1a-e; alkyl = Et, Pr, Pri, But, and -CH2-, respectively) have been prepared from the corresponding O-glycolaldehyde dimethyl acetals (2a-e) by acid hydrolysis.In anhydrous 1,4-dioxane in the presence of BF3*(Et2O)2, 1a-c were partially transformed into glycolaldehyde bis(dialkyl dithioacetals), 1d afforded trans-2,6-bis(tert-butylthio)-1,4-dioxane and 3,5-bis(tert-butylthio)-1,4-oxathiane, and 1e did not react.The acetals 2a-e were prepared from the appropriate glycolaldehyde dialkyl dithioacetal by O-alkylation with bromoacetaldehyde dimethyl acetal.
