Alkylations of chiral imidazolidinones derived from di- and triglycine and attempts at cyclisations to give cycloisodityrosines

Di- and triglycine derivatives (1-5) containing a 2-tert-butyl-1,3-imidazolidin-4-one moiety were prepared in rac. and enantiopure forms. By deprotonations with LiNR2 these imidazolidinones were converted to Li, Li2, and Li3/su
