  Palladium-catalysed cyclisation of chiral carbohydrate-derived geminal diacetates

  摘要：

  The Pd(0) and Pd(II)-catalysed cyclisation/functionalisation reactions of acyclic carbohydrate-derived 1,1-diacetoxy-2,7-diene and 1,1-diacetoxy-2-en-7-yne compounds proceeded in a stereospecific fashion to furnish chiral, multi-functionalised furanoid and cyclopentanoid products. The products contained valuable enolacetate moieties. which can be further elaborated to enable the facile entry to an array of substituted five membered ring compounds.

  The alarming resurgence of tuberculosis (TB) underlines the urgent need for development of new and potent anti-TB drugs. Towards this goal we herein report the design and synthesis of 2,3-dideoxy hex-2-enopyranosid-4-uloses as promising new anti-tubercular agents. These easily accessible, small molecules were found to exhibit in vitro activity against Mycobacterium tuberculosis H37Rv in a MIC range of 0.78 mu g/mL to 25 mu g/mL. A detailed SAR study on these hex-2-enopyranosid-4-uloses led to the identification of compound 5g (5007-724) which on the basis of low MIC (0.78 mu g/mL-M. tuberculosis H37Rv; 1.56 mu g/mL-MDR, SDR strains of M. tuberculosis; 0.78 mu g/mL-inhibition of intracellular replication of M. tuberculosis) and SI value of 13.5 has been identified as a promising lead molecule.

  The bromo unsaturated carbohydrates 30 and 9 were prepared from ethyl 4,6-di-O-acetyl-2,3-dideoxy-D-erythro-hex-2-enopyranoside (1a) and (7) by deacetylation followed by monosilylation with TBDMSCl and then alkylation with BrCH2CBr=CH2. The three analogues 6 and 10 were obtained using the same methodology after inversion at C-4 via a Mitsunobu reaction. The N- and C-analogues 4b and 5 were prepared by palladium alkylation of the carbonate 2d with TsNHCH(2)CBr=CH2 and (CO(2)Me)(2)CHCH2CBr=CH2, respectively. Treatment of the unsaturated carbohydrates 3a and 9 with a catalytic amount of Pd(OAc)(2)/PPh(3) in CH3CN/H2O in the presence of Bu(4)NHSO(4) and NEt(3) afforded the bicyclic compound 14a. The N- and C-analogues 14b and 14c were obtained using the same conditions and starting, respectively, from 4b and 5. On the other hand, treatment of the three derivatives 6 and 10 under these conditions gave the furanic structure 15. In the case of compound 30, performing the reaction in the presence of sodium formate yielded the bicyclic 2-deoxy carbohydrate 17.
