FIGURE 9.2 Natural sugar analogs with sulfur in the ring. [Pg.400]

The sugar alkaloid colchicoside and its synthetic sulfur analog thiocol-chicoside were acylated with esters of trifluoroethanol and with isopro-penylacetate in pyridine in the presence of the enzyme subtilisin from Bacillus subtilis (132). The 13C-NMR spectra of the ester alkaloids, which... [Pg.170]

An acyclic bisulfite adduct of 5-amino-3,5-dideoxy-D-ert/i fo-pentose was obtained on hydrolysis of its 1,2-isopropylidene acetal with sulfurous acid, and, on treatment with barium hydroxide, this gave an equilibrium mixture of the free sugar and its dehydration product, analogous to 33 34. Its aqueous solution shows a positive... [Pg.130]
