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.
