  Synthesis studies of structural analogues of tagetitoxin: 2-phosphate

  摘要：

  Synthetic approaches to structural analogues of tagetitoxin (1) are described. The successful route to analogue 3 (X=O) has, as a key step, protection of the cis-vicinal amino alcohol moiety of compound 7 as an N-benzylated cyclic carbamate (9). X-Ray crystallographic analyses of the hydrochloride of compound 7 and of the hydroxyacid 56 are reported. (C) 1999 Elsevier Science Ltd. All rights reserved.

  Starting 1,2,3,4-tetra-O-acetyl-6-O-tosyl-β-D-glucopyranose (3) was converted into 2,3,4-tri-O-acetyl-1-thio-6-O-tosyl-β-D-glucopyranose (6) via intermediate glycosyl bromide 4 and S-thiouronium salt 5. Treatment of compound 6 with sodium methoxide gave 1,6-anhydro-1-thio-β-D-glucopyranose (thiolevoglucosan 2a). The isomeric sulfoxides 7 and 8 were prepared by selective oxidation of thiolevoglucosan 2a with hydrogen peroxide or 3-chloroperoxybenzoic acid. The structure of new compounds was confirmed by ¹H and ¹³C NMR spectroscopy or by X-ray analysis; magnetic anisotropy of the sulfinyl and sulfonyl group has been discussed.

  Among 5-substituted cytosine analogues, 5-bromocytosine derivative (beta-isomer) 68 was found to be the most potent anti-HIV agent. In the case of purine derivatives, inosine analogue (beta-isomer) 78 was found to be the most potent anti-HIV agent in the 6-substituted purines and 2-amino-6-chloropurine derivative (beta-isomer) 90 showed the most potent activity in the 2,6-disubstituted purine series
