Selenium was inserted into the zinc carbon bond of aryl zinc halides to form corresponding zinc selenoates. They reacted in THF-HMPA with acylhalides to afford
One-pot reaction of aldehydes, ?haloketones and (phenylsulfonyl)acetonitrile promoted by SmI3 proceeded smoothly to give 1-cyano-1-phenylsulfonyl-2-aryl-3-aroyl
Four 5-deoxy-5-acyloxyiminoavermectin B1 derivatives 4a~d were synthesized via three steps from avermectin B1 and their biological activities were tested agains
A series of novel type of glycophosphate mimics are synthesized by Todd reaction and their structure were determined on the basis of NMR, ESI-MS.
A series of n
Phenyl sulfone-containing 2, 3-diarylindole derivatives were designed and identified to be selective COX-2 inhibitors. A convenient synthetic route was also de
