Synthesis of [1,2‐13C2,15N]‐ L ‐Homoserine and Its Incorporation by the PKS‐NRPS System of Fusarium moniliforme into the Mycotoxin Fusarin C

Fungal PKS/NRPS: [1,2-13C2,15N]-L-Homoserine has been prepared from [13C2,15N]-glycine in good yield. Incubation studies with cultures of the fungus Fusarium moniliforme confirm its intact incorporation into the pyrrolidinone ring of fusarin C.
