Discovery of the Cyclic Form of MRI pH‐Sensor Z‐OMPD Enables >5% 13C Hyperpolarization by SABRE

open access: yesAngewandte Chemie International Edition, EarlyView.
With “c‐OMPD”, we discovered a previously unknown 5‐membered lactol structure that arises from the homoaldol condensation of the central metabolite pyruvic acid. We demonstrate that the cyclization equilibrium is of crucial importance for OMPD's function as MRI‐based pH sensor and achieve for the first time 13C polarization levels (>5%) by SABRE in the
