A Selective Deprotection Strategy for the Construction of trans-2-Aminocyclopropanecarboxylic Acid Derived Peptides
摘要:
A procedure allowing access to unprecedented tripeptides containing a trans-2-aminocyclopropanecarboxylic acid residue in their central position has been established. The key features of the strategy are the use of a masked trans-2-aminocyclopropanecarboxylic acid monomer equivalent for C-terminal coupling and full N-Boc protection of all amide groups until the final step.

C4-building blocks for medicinal chemistry. The enzymatic kinetic resolution based synthesis of 1 and ent-1 utilises inexpensive, commercially available starting materials. It is based on enantiomeric resolution of rac-cyclopropane carboxylic esters using esterase from Streptomyces diastatochromogenes. Bothenantiomers of 1 were prepared selectively in high overall yield over nine steps, starting from

report a concise synthesis of 3-(trans-2-aminocyclopropyl)alanine, a component of belactosin A, using asymmetric alkylation of a glycine enolate in the presence of chiral phase-transfer catalysts to control the configuration at C2. Reaction of protected glycidol with triethyl phosphonoacetate (Wadsworth-Emmons cyclopropanation) is used for enantiospecific preparation of an intermediate cyclopropanecarboxylate
