Reactions of 1,2-disubstituted dienes 1-3 with enantiopure sulfinylquinones 4-6 occur with similar π-facial diastereoselectivities but reversed regiochemistry under thermal conditions and in the presence of ZnBr2. After spontaneous elimination

A stereoselective total synthesis of racemic myrocin C (1) has been achieved. Initial investigations produced cyclopropane-containing AB sector 22 via intramolecular ester-tethered Diels-Alder reaction of quinone 14 followed by internal alkylation of brom

The reaction of 2-siloxycyclo-1,3-dienes with E-vinyldiazoacetates in the presence of the bulky chiral dirhodium tetracarboxylate catalyst, Rh2(R-p-PhTPCP)4 results in an enantioselective [4+2] cycloaddition, in which three new stereogenic centers are formed. The [4+2] cycloadducts are generated as single diastereomers with high enantiocontrol (95–98 % ee). When the diene contains an additional stereogenic center, effective kinetic resolution can be achieved.
