Technical Notes:

1. Phenyl-BPE exhibits enhanced activity and selectivity over existing members of the BPE ligand family in rhodium catalysed asymmetric

2.This ligand is highly efficient for the hydrogenation of N-acyl aryl- enamides.

3.Molar substrate/catalyst ratios of up to 100,000/1 are achieved with excellent reactivity and enantioselectivity using

4.Ligand in the rhodium- catalyzed asymmetric hydroformylayion of thioamides

5.Ligand for asymmetric addition of allyl cyanide to kstones

6. Ligand for catalytic enantio- and diastereoselective aldol reaction of thioamides.

7- Organocatalytic 3+2 cycloaddition.

8. Site selective allenylation.

9 Asymmetric Phophonate addition.

10. Hydroboration of enamines.
