Chiral methylzine amino alkoxides

Dimethylzinc reacts with (S)-N-methylpyrrolidinyl-2-methanol, (R/S)-1-pheny l-2-(N-methylamino)-ethanol, and (S)-alpha,alpha-diphenyl-2-pyrrolidinyl-2- methanol in molar ratio 1:1 with formation of the corresponding methylzine amino alkoxides 1-3. As a consequence of the Zn-N-interaction new centres o f chirality containing asymmetric surrounded N-atoms are formed. Compounds 1-3 were characterized by their H-1 and C-13 nmr spectra. The crystal struc tures of 1-3 were determined by single crystal structur analysis. 1 and 2 a re trimeric in solid state, 3 is forming dimeric molecules.
