Synthesis of Plaunotol Derivatives and their Antibacterial Activities against Helicobacter pylori
摘要:
Plaunotol, a known antiulcer drug, has antibacterial activities against Helicobacter pylori. Plaunotol thiourea derivatives 2-4 and diol derivatives 6-10 were designed in search For a compound with high amtobacteroa; activities. Thiourea derivatives 2-4 were synthesized regioselectively using our effective synthetic route for plaunotol (1), and diol derivatives 6 10 were also synthesized. Their antibacterial activities against H. pylori are described and we found that the most potent antibacterial agent was Cl-thiourea derivative 2c. (C) 2001 Elsevier Science Ltd. All rights reserved.
A highly stereoselective synthesis of plaunotol and its thiourea derivatives as potent antibacterial agents against Helicobacter pylori
摘要:
Practical and high ly stereoselective synthesis of diterpene alcohol, plaunotol (1) and its thiourea derivatives 2a, 3a and 4a, via Z-selective Wittig reaction between cc-acetal ketone 5 and phosphonium salt 6 and their antibacterial activity against Helicobacter pylori are described.
