Automated, Multistep Continuous-Flow Synthesis of 2,6-Dideoxy and 3-Amino-2,3,6-trideoxy Monosaccharide Building Blocks

An automated continuous flow system capable of producing protected deoxy-sugar donors from commercial material is described. Four 2,6-dideoxy and two 3-amino-2,3,6-trideoxy sugars with orthogonal protecting groups were synthesized in 11–32 % overall yields in 74–131.5 minutes of total reaction time. Several of the reactions were able to be concatenated into a continuous process, avoiding the need for chromatographic purification of intermediates. The modular nature of the experimental setup allowed for reaction streams to be split into different lines for the parallel synthesis of multiple donors. Further, the continuous flow processes were fully automated and described through the design of an open-source Python-controlled automation platform.

Simple oxidation of 3-O-silylated glycals: Application in deblocking 3-0-protected glycals

A high yielding allylic oxidation of 3-O-siIylated glycals 5-10 with the reagent system PhI(OAc)2-TMSN3 is presented. The iodine(m) species generated under these conditions is a lot more effective for generating carbohydrate-derived 3-trialkylsiloxy-2,3-d

Approaches to the C-B-A trisaccharide of dihydroaclacinomycin by extending the chain from either side

Selective benzylation of L-fucal (1) under phase-transfer conditions gave the 3- and 4-monoethers 2 and 3, respectively. Two routes, the 'tail' or the 'head' addition are presented, both leading to the target molecule 9, a mimic of the C-B-A trisaccharide component of dihydroaclacinomycin. Addition of glycals 2 and 3, respectively, to the acetylated glycal (7) of amicetose used as glycosyl donor gave the disaccharide glycals 6 and 8. Alternatively, glycosylation of the 4-acetate (4) of 2 with the benzyl hex-2-enopyranoside derivative 10 gave the disaccharide derivative 11. In the first case, the final glycosylation step involves the addition of 10 to disaccharide glycal 8. In the second procedure, the disaccharide alcohol 12 is obtained by O-deacetylation of 11, and serves as the glycosyl acceptor for glycal derivative 7 to give the C-B-A precursor trisaccharide derivative 9.
