Astereoselective synthesis

Another option is the twofold Michael addition/SN-type sequence of which manifold versions have been published. Thus, Padwa s group reported on the di-astereoselective synthesis of bicydo[3.3.0]octenes [199], while in another approach by Hagiwara and coworkers various tricyclo[3.2.1.0]octane derivatives and similar bridged compounds have been constructed [200]. The group of Spitzner has also been engaged intensively in Michael/Michael/SN-type processes [201]. One such ex-... [Pg.104]

Chiral a-methylbenzylamine has frequently been used as a chiral auxiliary for di-astereoselective synthesis. This protecting group does not present any problem during its hydrogenolysis (Scheme 107). ... [Pg.1034]
