The reaction of iso-cinnamyl acetate with NaC(Me)(CO2Me)2, catalysed by Pd–‘MOP’ (MOP=2-methoxy-2′-diphenylphosphino-1,1′-binaphthalene) is known to proceed with a regiochemical memory effect that results in the predominant generation of th

The title compound 7 has been synthesized in a racemic form, using Suzuki coupling (8 + 15 → 16) as the key step. Pure enantiomer (S)-(-)-7 has been obtained by carbonylation of the known bromide (S)-(+)-12 followed by reduction of the resulting me

Reductive amination of 2-hydroxybenzaldehyde, using a combination of NaBH4 and (R)-[1,1'-binaphthalene]-2,2'-diamine, served as the key step in the synthesis of the potentially tetradentate ligands (R)-N,N'-bis(2-hydroxybenzyl)[1,1'-binaphthalene]-2,

The power of transition metal catalysis as a tool in organic synthesis is exemplified by the recent progress in the following areas: (i) diastereocontrol of Pd(0)-, Mo(0)-, and Ni(0)- catalyzed allylic substitution; (ii) Pd(0)-catalyzed asymmetric al

Tetrahydro analogues of [5]-, [6]- and [7]helicene have been easily prepared by intramolecular [2+2+2] cycloisomerization of appropriate triynes under CpCo(CO) 2 /PPh 3 or Ni(cod) 2 /PPh 3 catalysis. This nonphotochemical methodology allows enantiose
