Mechanism of stigmasterol dealkylation in insect [PDF]

open access: yesTetrahedron Letters, 1984
Abstract Deuterated stigmasterols (10, 11 and 12) were chemically synthesized and fed to silk-worm larvae. GC-MS analysis of the metabolites, cholesterol (4) and desmosterol (6), indicates the migration of 25-hydrogen to C-24 position during stigmasterol dealkylation.
