Axial-to-central chirality transfer in cyclization processes

Axial-to-central chirality transfer in cyclization processes Substrates, bearing axial chirality, can cyclize intra- or inter-molecularly with concomitant transfer of axial-to-central chirality to produce at least one stereocenter. In order to satisfy a strict definition of axial-to-central chirality transfer, the initial … Continue reading
