Tethered Glycoderivatives with Unsaturated Spacer: Synthesis and Characterization
摘要:
Williamson coupling of diisopropylidenated monosaccharides with trans-1,4-dibromo-2-butene gave five butenylene-bridged glycoderivatives. Their spectroscopic characterization includes infrared, mass, H-1 and C-13 NMR, correlation spectrometry, and heteronuclear multiple bond and quantum correlation measurements. This work is part of our effort to obtain chiral building blocks for the synthesis of bolaform and gemini-type surfactants with enhanced biodegradability and biocompatibility.
