In order to develop an efficient organocatalyst for the enantioselective N-H insertion reaction via carbene/carbenoid, the catalytic core of the cinchonaalkaloids was investigated. According to our working hypothesis of an eight-membered ring transition state in the N-H insertion reaction, two pairs of enantiomers related to 2-amino-1-phenylethanol were investigated for their chiral inducing potential
