Total synthesis of (±)-coerulescine and (±)-horsfiline

Summary Wittig olefination–Claisen rearrangement protocol was applied to obtain 3-allyl oxindole. This oxindole was then converted to (±)-coerulescine and (±)-horsfiline.

Zeolite catalyzed solvent-free one-pot synthesis of dihydropyrimidin-2(1H)-ones - A practical synthesis of monastrol

Summary A zeolite-catalyzed, simple, one-pot, solvent-free, cost effective, and environmentally benign process for the synthesis of dihydropyrimidones is described. This reaction is scaleable to multigram scale and the catalyst is recyclable. This methodology has resulted in an efficient synthesis of monastrol, a potent inhibitor of kinesin Eg5.
