Zinc chloride catalyzed reactions of chiral piperazine derivatives 4a–d with 1-alkynes and aldehydes give chiral propargylamines in 67–95 % yields with up to 99:1 dr. The chiral propargylamines are converted into chiral allenes by using zinc brom

Chiral allenes are readily accessed in a single pot operation in the reaction of terminal alkynes, aldehydes, chiral secondary amines, and zinc halides in good yields (up to 77% yield) and excellent enantioselectivities (up to 99% ee) in toluene at 1

A simple and convenient one-pot method for the reductive N-alkylation of ( R , R )- trans- 1,2-diaminocyclohexane by prochiral ketones using a Ti(O i Pr) 4 /NaBH 4 system to obtain the corresponding alkyl amine derivatives in 76–95% yields with goo

A new method of N-arylation of indole with (±)-trans-2,3-diarylpiperazines/copper(I) halide and aryl halides is described. Whereas electron-donating substituents in the phenyl group enhance the reactivity, the yields are lower with electron-withdraw
