We report the synthesis of an original unsymmetrical bismacrocycle bearing a carboxylic side-arm. Two ditferem synthetic pathways were investigated, both involving a Schotten-Baumann like reaction. The first route allowed us to obtain a mixture of compounds whilst the second one was direct and non-a

Under the action of a low-valent titanium reagent, imidazolidine derivatives were synthesized from imines and triethyl orthofbrmate in moderate yields. NMR spectroscopy was used to assign the configuration of the products.
## Abstract An improved classic Strecker synthesis was elaborated leading to racemic homopropargylglycine (Hpg) in 61% overall yield, while an asymmetric Strecker reaction produced Hpg and the higher homolog 2βaminoheptβ6βynoic acid in significantly higher yields and over 80% ee.
