Technical Notes:

1.Organocatalyst used in enantioselective intermolecular cross Rauhut-Currier reactions of activated alkenes with acrolein.

2.Organocatalyst used in aza-4+2 cycloaddition of N-sulfonyl-1-aza-1,3-dienes with vinyl ketones.

3.Catalyst for the enantioselective 3+2 cycloadditions of v-substituted allenoates with ß-perfluoroalkyl

enones.

4. Ligand for the direct Pd-catalyzed cross-coupling reaction of easily accessible secondary phosphine oxides and aryl bromides, which provides rapid access to P-chiral phosphine oxides.
