The synthesis of Ambrox®-like compounds starting from (+)-larixol. Part 2

Several Ambrox®-like compounds were synthesized in an enantiomerically pure form, and in relatively short procedures, starting from (+)-larixol. Triol 5 and enone 6 are important intermediates in these syntheses. The formation of Δ6-Ambrox®-type ethers was achieved by a new cyclization approach via ionization of the C(6)-allylic alcohol in ring B.
