S-(−)-2-acetoxymethyl-2,5-dihydrothiophene via enzymatic resolution
摘要:
For the resolution of (+/-)-2-hydroxymethyl-2,5-dihydrothiophene lipase-catalysed acetylation as well as hydrolysis and alcoholysis of the corresponding acetate were investigated, the best results being obtained in alcoholysis catalysed by lipase from Pseudomonas flurorescens with butanol in organic solvent.

Synthesis of 1-Deoxy-4-thio-D-ribose starting from Thiophene-2-carboxylic acid
摘要:
The de novo synthesis of 1-deoxy-4-thio-D-ribose starting from thiophene-2-carboxylic acid is described, The key step is the cis-dihydroxylation of S-2-acetoxy-2, 5-dihydrothiophene, which is obtained by enzymatic alcoholysis. (C) 1997 Elsevier Science Ltd.
