Na, Ho Seong,Choi, Jaehyuck,Yu, Jaehoon,Shin, Kye Jung,Yoo, Kyung Ho,Kim, Dong Jin,Park, Sang Woo

, p. 2365 - 2378 (2007/10/03)

The synthesis and enzyme assay of 2,8-dihydroxyindolizidines (5) were described. Four diastereomers of these were prepared from trans-4-hydroxy-L-proline (6) which is commercially available amino acid. Among synthetic compounds 5a1 and 5b2 showed medium potent inhibition to α-amyloglycosidase, while 5a2 displayed medium activity to α-glucosidase.
