Progress in 1,3-dipolar cycloadditions in the recent decade: An update to strategic development towards the arsenal of organic synthesis
2016, TetrahedronCitation Excerpt :Highly regioselective 1,3-dipolar cycloadditions between d-arabinose derived nitrones 543 and d-mannitol derived trans-olefins 544 have been utilized to synthesize isofagomine-pyrrolidine hybrid sugars 545, hydroxymethylated analogues of (−)-steviamine 546 and 547, and analogues of (+)-hyacinthacine 548 and 549. The cycloaddition reaction followed a reversal of regioselectivity in comparison to acrylates, and this provided the platform for synthesizing the newly designed molecules (Scheme 133).190 The newly synthesized compounds have been further tested against commercially available glycosidases to study their enzymatic activity and some of them showed good and selective glycosidase inhibition.
