We report an efficient and highly diastereoselective oxy-Cope/ene/Claisen reaction
for the synthesis of decalin frameworks possessing four contiguous stereogenic centers.
A detailed mechanistic investigation and its application to a short and protecting
group free synthesis of desdimethyl ambliol B are presented.
