## Abstract Reaction of adriamycinone with excess ^14^CH~3~Mgl and periodate cleavage of the resulting glycol (5) affords daunomycinoneโ14โ^14^C (6). Bromination and hydrolysis of 6 gives adriamycinoneโ14โ^14^C (8). Coupling of 6 and the 14โ0โpโanisyldiphenylโmethyl derivative (9) with 1โchloroโ3โN
The synthesis of lanosterol [la] and desmosterol [Ira] Iabeled with 14C in the 25 position by a Wittig reaction between triphenyl-214C isopropylidene-phosphorane [IVb] and the corresponding aldehydes are described. The specijic activities obtained are, respectively, 0.539 mClmM and 0.752 mClmM and t
