N-Aminoazetidinecarboxylic Acid: Direct Access to a Small-Ring Hydrazino Acid
摘要:
A short and efficient synthesis of the previously unknown N-aminoazetidinecarboxylic acid has been established using a photochemical [2 + 2] cycloaddition strategy starting from 6-azauracil. Chiral derivatization with a nonracemic oxazolidinone provided access to both en-antiomers of the title product.

Peptide formation on the N-terminal of 1-aminoazetidine-2-carboxylic acid is rendered problematic due to a ring opening reaction. However C-terminal development is possible and two diastereomeric mixed hydrazino dipeptides were prepared. Solution-state studies of these compounds suggest the presence of intramolecular hydrogen bonding, consistent with a hydrazino turn, and the crystal structure of one
