Diastereoselective Michael Additions of Chiral Imidazolidines to Trityl Enones

The enolates A and C of t-butyl (R)-2-t-butyl-3-methyl-4-oxo-1-imidazolidinecarboxylate (1, Boc-BMI) and of 1-t-butyl 5-methyl (2R,5S)-2-t-butyl3-methyl-1,5-imidazolidinedicarboxylate (3) and t-butyl (R)-2-t-butyl-5-lithio-3-methyl-1-imidazolidinecarboxyl

Tritylketones and Tritylenones. Contribution to the Sterically Enforced Michael Addition and to the Diastereoselective Aldol Addition

Tritylketones are prepared from trityllithium and aldehydes, with subsequent CrO3 oxidation (Scheme 1, 2a-f).Tritylenones are obtained from the saturated ketones and aldehydes or ketones, preferably by (CH3)3Al-mediated aldol addition with subsequent dehy
