TY - JOUR A1 - Wessig, Pablo A1 - Pick, Charlotte A1 - Schilde, Uwe T1 - First example of an atropselective dehydro-Diels-Alder (ADDA) reaction JF - Tetrahedron letters N2 - A new concept of a stereoselective synthesis of axially chiral biaryls, formed in the course of the dehydro-Diels-Alder (DDA) reaction, has been disclosed. It is based on asymmetric induction of the newly formed chirality axis by a chirality center, which is present in the two synthesized DDA reactants. Depending on the different length of the linkers joining the alkyne moieties the DDA reaction may be triggered photochemically or thermally, where only the thermal variant was stereoselective.
