DestomycinC, a pseudo-trisaccharideantibiotic of orthosomycin family was synthesized via spiro-orthoester formation between 5-o-(β-D-mannopyranosyl)-2-deoxystreptamine and 6-amino-6-deoxyheptonolactone derivatives.
Destomycin C 是一种正霉素家族的假三糖抗生素,是通过 5-o-(β-D-吡喃甘露糖基)-2-脱氧链胺和 6-氨基-6-脱氧庚内酯衍生物之间的螺原酸酯形成合成的。

Simple primary alkyl triflates and those derived from several monosaccharides are cleanly displaced by diethyl (lithiodifluoromethyl)phosphonate to provide the corresponding (alpha,alpha-difluoroalkyl)phosphonates in minutes at -78-degrees-C.
