The stereoselective Diels-Alder reaction between an optically active 1,4-dimethylcycloheptadiene and acrolein was effectively promoted by TBSOTf to produce a bicyclo[3.2.2]nonene derivative bearing two quaternary carbons. Seven additional transformations from the obtained bicycle delivered the C 2-symmetric bicyclo[3.3.2]decene derivative, a key intermediate in our synthetic study of ryanodine. © 2013 Tabuchi et al.
