The chemical synthesis of swainsonine [(1S,2R,8R,8 alpha R)-trihydroxyindolizidine] from trans-1,4-dichloro-2-butene was previously described [Adams, C. E., Walker, F. J., & Sharpless, K. B. (1985) J. Org. Chem. 50, 420-424]. A modification of that synthesis provided two other isomers, referred to

Alkylation of adenine (5a) or 2-amino-6-chloropurine (5b) with excess trans-1,4-dichloro-2-butene (4), effected by K2CO3 in dimethyl sulfoxide or tetra-n-butylammonium fluoride in tetrahydrofuran, led in 90-95% regioselectivity to 9-alkylpurines 6a and 6b. The title compounds 2a and 2b were obtained by
