3 in this cyclization step may be due to its reversible coordination with the double bond, thus activating the conjugate addition of either the phosphine or the formed enolate. For metal-promoted Michael reactions requiring the presence of free phosphine, see: Gómez-Bengoa, E.; Cuerva, J. M.; Mateo, C.; Echavarren, A. M. J. Am. Chem. Soc. 1996, 118, 8553 (and references cited therein).
