REGENERATION OF KETONES FROM SEMICARBAZONES BY LEAD TETRA-ACETATE : A NOVEL PREPARATION OF 18-HYDROXYCORTICOSTERONE
Kirk, David N.,Slade, Christopher J.
, p. 651 - 654 (2007/10/02)
Lead tetra-acetate in acetic acid has been used to cleave a 3-semicarbazone in a novel preparation of 18-hydroxycorticosrerone, designed to avoid strongly acidic conditions.
