Synthesis of enantiopure α-Tfm-proline and α-Tfm-pipecolic acid from oxazolo-pyrrolidines and -piperidines

Enantiopure α-Tfm-proline and α-Tfm-pipecolic acid were synthesized starting from commercially available diesters and ethyl trifluoroacetate. A Strecker type reaction on intermediate chiral Tfm-oxazolo-pyrrolidine and -piperidine provided the corresponding nitrile precursor of enantiopure (R) and (S) α-Tfm-proline and α-Tfm-pipecolic acid. The C-terminal peptide coupling reaction of α-Tfm-pipecolic acid has been successfully achieved.

(2R,1'S,2'R)- And (2S,1'S,2'R)-3-[2-mono(di,tri)fluoromethylcyclopropyl] alanines and their incorporation into hormaomycin analogues

Efficient and scalable syntheses of enantiomerically pure (2 R ,1' S ,2' R )- and (2 S ,1' S ,2' R )-3-[2-mono(di,tri)fluoromethylcyclopropyl] alanines 9a - c , as well as allo-D-threonine ( 4 ) and ( 2 S,3R)-β-methylphenylalanine (3), using the Belokon' approach with (S )- and (R )-2-[( N-benzylprolyl)amino]benzophenone [(S)- and (R)-10 ] as reusable chiral auxiliaries have been developed. Three new fluoromethyl analogues of the naturally occurring octadepsipeptide hormaomycin ( 1 ) with (fluoromethylcyclopropyl) alanine moieties have been synthesized and subjected to preliminary tests of their antibiotic activity.
