filter terms:

Nitro-substituted donor-acceptor cyclopropanes react with salicylaldehydes in the presence of cesium carbonate in water to give new chromane derivatives. The reaction takes place through in situ formation of allene intermediates from the cyclopropanes and subsequent Michael-initiated ring closure of the intermediates with salicylaldehydes.
