Gaia:	Title screen The outcome of the nucleophilic opening of 3-O-benzoyl-β-d-arabinofuranose 1,2,5-orthobenzoate with 4-(ω-chloroalkoxy)phenols (SnCl4, CH2Cl2, -25 °C) unusually strongly depends on the length of the methylene chain of the nucleophile. The presence of one extra methylene group in the molecule of 4-(3-chloropropoxy)phenol [as compared to 4-(2-chloroetoxy)phenol] results in four-fold reduction in the reaction time and five-fold increase in the yield of a selectively protected monosaccharide glycoside with a hydroxy group at C-5, which is a valuable building block for the synthesis of oligoarabinofuranosides related to mycobacterial arabinans. Possible reasons and consequences of this finding are discussed. Режим доступа: по договору с организацией-держателем ресурса
