Derivatives of azidosugars were shown to be stable under conditions of trityl-cyanoethylidene condensation. Tritylated 1,2-O-(1-cyano)ethylidene derivative of 2-azido-2-deoxy-beta-D-mannopyranosyl-(1----4)-L-rhamnopyranose was used as a starting material for the synthesis of [----3)-beta-D-ManNAc-(1----4)-alpha-L-Rha-(1----]n, the O-specific polysaccharide of Pseudomonas aeruginosa X (Meitert).
叠氮糖衍生物在三苯甲基-亚乙基腈缩合条件下被证明是稳定的。2-叠氮基-2-脱氧-β-D-甘露吡喃糖基-(1→4)-L-鼠李吡喃糖的三苯甲基化1,2-O-(1-氰基)亚乙基衍生物被用作合成铜绿假单胞菌X（迈特尔特）的O-特异性多糖[→3)-β-D-甘露糖胺-(1→4)-α-L-鼠李糖-(1→]n的起始原料。
