✦ Synopsis
^13^C‐ and ^15^N‐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 ^15^N‐NMR, and ^13^C‐NMR. spectroscopy. The simultaneous coupling of ^13^C(11) with ^15^N(5) and ^15^N(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 ^15^N is described.
