|Title:||Chemical transformation of andrographolide†|
Sharma, R P
|Abstract:||Tosylation of andrographolide 1, with p-TsCl pyridine furnishes compounds 3 and 4. The reaction of 1 with in situ generated nickel boride yields compounds 6 and 8. Monotosylation of 6 followed by reaction with NaI refluxing in acetone furnishes the iodide 13. But all attempts to generate an oxetane moiety in 13 corresponding to compund 2 failed.|
