Bis(tributyltin)oxide (BBTO) has been utilized for the first time for the deprotection of steroid esters. The best results were obtained for 3β-esters, in particular the selective hydrolysis of the 3β-acetyl group in 3β,6α-diacetoxy-5α-pregnan-20-one to give 6α-acetoxy-3β-hydroxy-5α-pregnan-20-one.
