Abstract
The impact of a remote aromatic nucleus on the stereochemical outcome of the conjugate addition of α-sulfonylallylic carbanions to an α,β-unsaturated ester was investigated. α-Regioselectivity coupled with anti-diastereoselectivity is accompanied by a prominent preference for relative configuration 3 over 4. The 9-anthryl moiety has shown itself greatly superior over all other groups in this bias. A lithium ion–aromatic π interaction has been postulated as decisive for the remote transmission of chirality.

Abstract
An efficient total synthesis of (+/-)-alantrypinone 4 by hetero Diels-Alder reaction of a novel pyrazine diene 9 with either a functionalized 3-alkylideneoxindole or 3-methyleneoxindole itself is described. The Diels-Alder reactions provide both the desired regiochemistry and exo selectivity. An interesting anionic equilibration between alantrypinone 4 and its epimer 31 or between its ester analogues 23 and 24 has been demonstrated, and a mechanism has been proposed.
