The thiol-disulfide dynamic interchange reaction mediated by 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) was extensively studied. By this synthetic method sulfides can be prepared successfully within seconds in high yields at room temperature from stable and readily available disulfides and an alkylating agent. The
Direct organocatalytic Mannich-type reactions of thioesters provide for the expedient and diastereoselective synthesis of protected beta-amino acids. A variety of thioesters were found to be reactive with different imines under mild conditions to provide beta-amino acids in good yields. This

With the new chiral phosphine ligand DBUP, obtained from DBU and Ph(2)PCl, a remarkable anion effect was observed on the diastereoselective formation of the bischelated complexes [Ni(DBUP)(2)](X)(n) (X = Cl, Br, n = 2; X = NiCl(4), n = 1)
Lipid extraction is a critical step in the development of biofuels from microalgae. Here a new procedure was proposed to extract hydrocarbons from dried and water-suspended samples of the microalga Botryococcus braunii by using switchable-polarity solvents (SPS) based on 1,8-diazabicyclo-[5.4.0]-undec-7-ene

DBU-promoted cyclization of ortho-(3-hydroxy-1-alkynyl)benzamide is presented, providing an efficient method for the synthesis of trans-3,4-dihydroisoquinolin-1(2H)-ones and (E)-4-(1-alkenyl)isoquinolin-1(2H)-ones under mild conditions.
