Remarkable threo selectivity is observed in the reaction of aldehydes with tm-and c&s-1-bromo-2-butene with the aid of chromium(H) salts. Solvent effect as well as the synthetic application is discussed. How to attain acyclic stereoselection is of great importance in modern synthetic methodologies.
A general synthetic procedure for the preparation of multisubstituted phenanthrolines is presented. Bromination of 1,10-phenanthroline at the 3 and 8 positions, followed by Suzuki coupling reaction and subsequent methylation afford the di-, tri and tetra-substituted phenanthrolines in good yields. T
