  Synthesis of 3,3′-neotrehalosadiamine and related 1,1′-aminodisaccharides using disarmed, armed, and superarmed building blocks

  摘要：

  Here we report a high yielding, stereoselective synthesis of the naturally occurring 1,1'-disaccharide neotrehalosadiamine (NTD) and some related analogs. Following an eleven-step sequence, seven of which did not require chromatographic separation, NTD was generated in 60% overall yield from the inexpensive, commercially available precursor 1,2:5,6-di-O-isopropylidene-alpha-D-glucofuranose. The key alpha,beta-linkage of NTD was formed in a highly stereoselective manner by taking advantage of the participating effect of the acyl group at O-2 of the donor glycoside. The influence of electronic effects of disarmed, armed, and superarmed glycosyl donors and acceptors on the outcome of 1,1'-glycosidation was also observed. Antibacterial studies using NTD and its analogs show detectable but weak antistaphylococcal activity. (c) 2012 Elsevier Ltd. All rights reserved.
