, p. 3008 - 3016 (2005)
The two new analogues 2 and 3 of the natural dipeptide antibiotic TAN 1057 A/B (1), both with cyclopropyl containing β-amino acid side chains, were prepared. The synthesis of the corresponding β-amino acids in appropriately protected form (4-Z3

, p. 867 - 882 (2007/10/02)
Alkyl 2-chloro-2-cyclopropylideneacetates 2 serve as universal starting materials for a new general synthesis of cyclopropylglycines by a simple three- to four-step methodology. 1,4-Addition of nucleophiles, substitution with azide ion, and mild catalytic
