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)

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

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

[reaction: see text] DBU-catalyzed reactions of salicylic aldehydes with 3-methylpenta-3,4-dien-2-one, 3-benzylpenta-3,4-dien-2-one, or ethyl 2-methylbuta-2,3-dienoate gave the corresponding functionalized 2H-1-chromenes in good to excellent yields and good diastereoselectivities in some cases in DMSO, respectively.

A pH-controlled fluorescence switch based on a core-substituted naphthalenediimide compound (NDI-DBU) was constructed. The novel pentacyclic compound (NDI-DBU) was derived from naphthalenediimide (NDI) and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in only one synthetic operation, catalysized by CuI.
