摘要：NOVELTY - A polycyclic amide derivative (I), is new. USE - New polycyclic amide derivative is used as nuclear magnetic resonance imaging contrast agent. ADVANTAGE - The polycyclic amide derivative provides nuclear magnetic resonance imaging contrast agent having excellent thermodynamic stability, imaging effect and biocompatibility, and high hydration constant. DETAILED DESCRIPTION - A polycyclic amide derivative of formula (I), is new. R1,R2=H, 1-24C alkyl, aryl or heterocyclyl. An INDEPENDENT CLAIM is included for preparation of compound (I).
