Biradical formation from acyclic conjugated eneyne-allene system related to neocarzinostatin and esperamicin-calichemicin
TL;DR: Acyclic conjugated allenylphosphine oxide 4b prepared by three step operations was stable at ambient temperature and underwent Bergman type cyclization to form biradical 5b at 37 °C as discussed by the authors.
Journal ArticleDOI
Concerted reactions that produce diradicals and zwitterions: electronic, steric, conformational, and kinetic control of cycloaromatization processes.
TL;DR: The data suggested that products from both polar and free radical reaction pathways arise either from a single reactive intermediate or from a pair of rapidly equilibrating species, which suggests that the partitioning between the diradical and zwitterionic pathways occurs after the rate-determining TS.
