Aldol Reaction,e.g.
O HO 10 mol % L7 P-OEt 30 mol % PMBA OET Toluene, 0 °C CH3CHO -OEt OET
Henry Reaction,e.g.
10 mol % L8 PhH * CH3NOZ N O2 THF, -20 °C PH 92% ee, 90% yield
Hydroxyalkylation Reaction,e.g.
F3C, OH CO2Et HO COZET 5 mol % Cat 5 mol % Cat Et,0,-8 °C CD Et20,-8 °C CN 95% ee, 99% yield F3CC02Et 90% ee, 98% yield HT "VN HA HO, LN HO. V N Cinchonine (CN) Cinchonidine (CD)
dehydrogenation,(it is normal H₂ eliminaion via bio pathway)

Wagner-Meerweein rearrangement,e.g.
