- Enzymatic resolution of cyclic N-Boc protected β-aminoacids
-
Methyl and ethyl esters of N-Boc homoproline, homopipecolic acid and 3-carboxymethyl-morpholine were kinetically resolved by hydrolysis catalysed by Burkholderia cepacia lipase to give the corresponding acids and residual esters in enantiomeric excesses better than 99% (E > 100).

- Decarboxylation Reaction. X. Introduction of a Carbon unit at the α-Position of Amines by Reaction of Hexahydro-1,3,5-triazines with Carboxylic Acids
-
An efficient method for introducing a carbon unit at the α-position of alicyclic amines is described.The method involves the reaction of monocyclic or tetracyclic hexahydro-1,3,5-triazines with trichloroacetic acid, cyanoacetic acid, malonic acid and their derivatives, which are introduced into the α-position of amines in the decarboxylated form.Keywords --- 1,3,5-trialkylhexahydro-1,3,5-triazine; trimer of alicyclic imine; decarboxylation; β-amino acid; carboxylic acid
