Recent advances in synthetic approaches for medicinal chemistry of C-nucleosides
Beilstein J Org Chem 2018 Apr 5;14:772-785.PMID:29719574DOI:10.3762/bjoc.14.65.
C-nucleosides have intrigued biologists and medicinal chemists since their discovery in 1950's. In that regard, C-nucleosides and their synthetic analogues have resulted in promising leads in drug design. Concurrently, advances in chemical syntheses have contributed to structural diversity and drug discovery efforts. Convergent and modular approaches to synthesis have garnered much attention in this regard. Among them nucleophilic substitution at C1' has seen wide applications providing flexibility in synthesis, good yields, the ability to maneuver stereochemistry as well as to incorporate structural modifications. In this review, we describe recent reports on the modular synthesis of C-nucleosides with a focus on D-Ribonolactone and sugar modifications that have resulted in potent lead molecules.
Carbocyclic analogues of D-ribose-5-phosphate: synthesis and behavior with 5-phosphoribosyl alpha-1-pyrophosphate synthetases
Bioorg Med Chem 1996 Jul;4(7):1077-88.PMID:8831979DOI:10.1016/0968-0896(96)00090-9.
The synthesis of cyclopentyl and cyclopentenyl analogues of the alpha-anomer of D-ribose-5-phosphate from D-Ribonolactone and D-ribose is described. These analogues, which have the same absolute configuration as D-ribose-5-phosphate, were incubated with PRPP synthetases in an attempt to prepare the corresponding carbocyclic PRPP analogues. The carbocyclic ribose-5-phosphate analogues were found to be inhibitors, rather than substrates, for 5-phosphoribosyl alpha-1-pyrophosphate synthetases of both bacterial and human origin. The inhibitory behaviour of the analogues is described.
A synthetic route to 3-C-alkyl (or 3-C-phenyl-) 2,3-dideoxy-D-erythro-pentono-1,4-lactones: intermediates in the synthesis of 2(3H)-furanones
Carbohydr Res 1994 Feb 3;253:207-23.PMID:8156548DOI:10.1016/0008-6215(94)80066-9.
A series of 3-C-alkyl- (and 3-C-phenyl-) 2,3-dideoxy-D-erythro-pentono-1,4-lactones, compounds which are important in the synthesis of modified nucleosides and antibiotic sugars, were synthesized from D-Ribonolactone. By a route that proceeded via 5-O-protected D-Ribonolactone, 5-O-protected 2,3-dideoxy-D-glycero-pent-2-enono-1,4-lactones were synthesized and reacted with R2CuLi or a complex PhSCu(RMgBr)n to give respectively the 3-C-alkyl or 3-C-phenyl compounds. Details of the preparation of the O-protected intermediates, as well as the selection of the organometallic reagents, are provided.
Stereoselective synthesis of 4'-selenonucleosides using the Pummerer glycosylation reaction
Carbohydr Res 2008 Jul 21;343(10-11):1790-800.PMID:18316068DOI:10.1016/j.carres.2008.02.014.
The syntheses of four selenonucleosides, namely 4'-beta-selenoadenosine, -cytidine, -thymidine, and -uridine are described. Commercially available D-Ribonolactone was converted to the key intermediate 1,4-anhydro-4-seleno-D-ribitol in seven steps in overall excellent yield. Oxidation of the seleno-d-ribitol with MCPBA gave a single diastereomeric selenoxide in excellent yield, which upon Pummerer reaction in the presence of silylated purine or pyrimidine bases gave stereoselectively the corresponding 4'-beta-selenonucleosides. The stereochemistry at the anomeric center was determined by means of 1D-NOE experiments.
Toward a general strategy for the synthesis of 3,4-dihydroxyprolines from pentose sugars
J Org Chem 2002 Jun 28;67(13):4466-74.PMID:12076143DOI:10.1021/jo025538x.
A general strategy is proposed, wherein a pentose sugar gamma-lactone can be converted, via a series of nine reactions, to a 3,4-dihydroxyproline, suitably protected for use in peptide synthesis. Thus, D-Ribonolactone (6) has been converted to N-fluorenylmethoxycarbonyl-3,4-di-O-tert-butyldimethylsilyloxy-D-2,3-cis-3,4-cis-proline (7) in 18.9% overall yield. Likewise, L-arabinonolactone (11) has been converted to N-fluorenylmethoxycarbonyl-3,4-di-O-tert-butyldimethylsilyloxy-L-2,3-cis-3,4-trans-proline (36) in 13.7% overall yield and L-lyxonolactone (12) to N-fluorenylmethoxycarbonyl-3,4-di-O-tert-butyldimethylsilyloxy-L-2,3-trans-3,4-cis-proline (37) in 11.2% overall yield. These building blocks have also been fully deprotected to give the free amino acids. We believe that this series of reactions ought to be applicable to the synthesis of any of the eight stereoisomers of 3,4-dihydroxyproline, by judicious selection of the pentose starting material.
