Diversity oriented concise asymmetric syntheses of l-2,3-trans-3,4-cis-dihydroxyproline and (3S,5S)-3,4,5-trihydroxypiperidine have been developed from (R)-glycidol. The key step of the synthesis is Sharpless asymmetric dihydroxylation on enantiomerically pure TBDMS protected allylic alcohol 14 which generates the triol intermediate 15 in excellent de. The (2R,3R,4S)-2,3-dihydroxypentanoate derivative 15 was subsequently converted to natural pyrrolidine azasugar 1 and non-natural piperidine azasugar 4 under cascade reaction conditions in good yields.

Synthesis and Absolute Stereochemical Reassignment of Mukanadin F: A Study of Isomerization of Bromopyrrole Alkaloids with Implications on Marine Natural Product Isolation
van Rensburg, Michelle,Copp, Brent R.,Barker, David
, p. 3065 - 3074 (2018/07/06)
Synthesis of both enantiomers of mukanadin F was achieved by using a seven step synthesis. Comparison of the optical rotation data of synthetic samples to that reported for the isolated natural product determined that the absolute configuration of the natural product is 9S and not the reported 9R. Further studies established that the reported low magnitude of optical rotation in the isolated sample is due to compounds of this type undergoing isomerization and racemization under benign laboratory conditions. Additionally the synthetic methods developed were applied to synthesize mukanadins B and D.

Several acyclic hydroxy-methylthio-amines with 3-5 carbon atoms were prepared and coupled via a methylene link to 9-deazaadenine. The products were tested for inhibition against human MTAP and Escherichia coli and Neisseria meningitidis MTANs and gave Ki values as low as 0.23 nM. These results were compared to those obtained with 1st and 2nd generation inhibitors (1S)-1-(9-deazaadenin-9-yl)-1,4-dideoxy-1,4-imino-5-methylthio-d-ribitol (MT-Immucillin-A, 3) and (3R,4S)-1-[9-deazaadenin-9-yl)methyl]3-hydroxy-4- methylthiomethylpyrrolidine (MT-DADMe-Immucillin-A, 4). The best inhibitors were found to exhibit binding affinities of approximately 2- to 4-fold those of 3 but were significantly weaker than 4. Cleavage of the 2,3 carbon-carbon bond in MT-Immucillin-A (3) gave an acyclic product (79) with a 21,500 fold loss of activity against E. coli MTAN. In another case, N-methylation of a side chain secondary amine resulted in a 250-fold loss of activity against the same enzyme [(±)-65 vs (±)-68]. The inhibition results were also contrasted with those acyclic derivatives previously prepared as inhibitors for a related enzyme, purine nucleoside phosphorylase (PNP), where some inhibitors in the latter case were found to be more potent than their cyclic counterparts.
