PPh3-catalyzed domino reaction: a facile method for the synthesis of chroman derivatives.
A novel domino reaction catalyzed by triphenylphosphine was developed for synthesis of the highly functionalized chroman derivatives. The first example that the gamma-CH(3) of allenoate undergoes cyclization to form chroman derivates was reported.
