Synthesis of Substituted 1,7-Diaza-12-crown-4 Containing Oxazolines and Its Application

  • Published:2003-04-25

New bibracchiral lariart crown ethers la ~lc were synthesized by treatment of 1,7-doaza-12-crown-4 with chiral oxazolines 2a~2c .2a~2c were prepared from amino alcohols and triethyl orthochloroacetate. Cu (Ⅱ) complexes of la~lc were applied to the asymmetric cyclopropanation of 1,1-diphenyl ethylene with alkyl diazoacetate.
