Selective Synthesis and Structure of 6-Arylvinyl-2- and 4-Glucosyl-1,2,4-triazines of Expected Interesting Biological Activity
摘要:
The 6-beta-arylvinyl-2- and 4-glucosyl-3-thioxo-2,3-dihydro-1,2,4-triazin-5(4H)-ones were synthesized with high selectivity using the recently developed amino protecting group strategy. The structure of these new glucosides was established chemically, and spectroscopically. Also, some interesting chemical transformations and rearrangements were observed.
