Chiral hydrazones 1 reacted with aryl- or alkyl-lithiums at -78 degrees C in a short reaction time, within 10 min, to afford arylated or alkylated chiral hydrazines 3 with extremely high diastereoselectivity (up to >99% de) and high chemical yields. The hydrazines are readily converted to chiral ami
