- Synthesis of N,N′-Dialkylated Cyclohexane-1,2-diamines and Their Application as Asymmetric Ligands and Organocatalysts for the Synthesis of Alcohols
-
A series of N,N′-dialkylated derivatives of (1R,2R)-cyclohexane-1,2-diamine were synthesized, and a new approach to the one-pot preparation of this type of amine was demonstrated. The prepared diamines were used as organocatalysts for the two-step synthesis of α-hydroxy γ-keto esters from arenes, chlorooxoacetates, and ketones; they were also used as chiral ligands for Meervein-Ponndorf-Verley reductions and Henry reactions.

- Reliable and versatile synthesis of 2-aryl-substituted cinnamic acid esters

2-Aryl-substituted phosphono acetates can be readily synthesized by a four-step sequence from the respective arenes. Succeeding Horner-Wadsworth- Emmons olefinations provide stereoselectively the 2-aryl cinnamic acid esters even when sensitive moieties are involved. Georg Thieme Verlag Stuttgart.
