摘要

Abstract The latest route to Ambrox®(1) starting from sclareol (2) proceeds through an oxy ketone 4 (Scheme 1). A new practical synthesis of the key intermediate 4 is described; it is equivalent to a partial oxidative degradation of sclareol (2) with peracetic and periodic acids (Scheme 2). The final product of the Baeyer [BOND] Villiger oxidation of the oxy ketone 4 with commercial peracetic acid is decisively dependent on the reaction conditions ...
