On the steric course of the microbial generation of (Z6)-gamma-dodecenolactone from (10R, S) 10-hydroxy-octadeca-(E8, Z12)-dienoic acid

(Z6)-gamma-dodecenolactone samples produced endogenously inFusariumpoae and biogenerated from (10R, S) 10-hydroxy-octadeca-(E8, Z12)-dienoic acid inCladosporiumsuaveolens show (R) and (S) configurations, respectively.
