A series of novel 3,4,5,6-tetrahydropyrimidinium salts, the precursor of N-heterocyclic carbene, were synthesized in high yields using a two-step procedure starting from commercially available amino alcohols. In situ prepared corresponding carbenes were tested in palladium-catalyzed C(sp3)?H arylation of 4-benzylpyridine with aryl bromides, affording triarylmethane derivatives in high yields.

Syntethic routes to macrocycles derived from (S)-phenyl alanine and (S)-cysteine have been developed.The catalyzed coupling of the Grignard reagent of 1-chloro-1-phenylethane and vinyl bromide in the presence of these ligands proceeds usually in good yields and in enantiomeric excesse (e.e.) of up to 46percent.
