DOI: 10.1002/ajoc.202500615
Abstract: A synthetic method that relies on base‐promoted allylation(propargylation)/propargyl‐allenyl isomerization/dehydro‐Diels−Alder cascade of 1,3‐enynyl alcohols for the synthesis of structurally diverse phthalan derivatives under metal‐free mild reaction conditions is described. Moreover, the protocol could be further expanded… read more here.
