, p. 1707 - 1710 (2004)
A new Schiff-base with two stereogenic centers has been prepared and its titanium complex applied to catalyze the pinacol coupling of aldehydes, which afforded pinacols in high yield, excellent diastereoselectivities, and high enantioselectivities.
Synthesis of New Optically Active Crown Ethers
Dehmlow, Eckehard V.,Knufinke, Volker
, p. 1091 - 1094 (2007/10/02)
Optically active crown ethers 1a-11, 2, 3a,b, 4a,b, 5a,b and the analogue 6 are synthesized.The efficiency of these compounds as phase-transfer catalysts for a series of enantioselective reactions will be tested.This will be described in a following publication. Key Words: Crown ethers, chiral, optically active / Phase transfer catalysts
