- Abstract
13C- and 15N-NMR.-Spectroscopic Studies on ( 6RS)-5, 10-Methylene-5, 6, 7, 8-tetrahydro- L-folic Acid; Unequivocal Proof of thier Structure The existence of a 5, 10-methylene bridge in the title compound has been established with the help of 15N-NMR, and 13C-NMR. spectroscopy. The simultaneous coupling of 13C(11) with 15N(5) and 15N(10) proves that C(11) must be bound as a methylene bridge to both N-atoms. Some other aspects of the NMR. spectra of the compound are discussed. Synthesis of the title product with the label 15N is described.
