Masakatsu Shibasaki was born in 1947 in Japan. In 1974 he received his Ph. D. Deg ree from the University of Tokyo. After then he did postdoctoral studies with professor E. J. Corey at Harvard University. In 1977, he returned to Japan and joined Teikyo University as an associate p rofessor. In 1983 he moved to Sagami Chemical Research Center as a group leader and in 1986 took up a professorship at Hokkaido Unive rsity, before returning to the University of Tokyo as a professor i n 1991.His research interests include asymmetric catalysis and medi cinal chemistry of biologically significant compounds. He has received Fluka Prize( 1996), the Elsevier Award for Inv entiveness in Organic Chemisty(1998), the Pharmaceutical Society o f Japan Award(1999), ACS Award (2002), the National prize of Pur ple Ribbon(2003), Japan Academy Prize(2005), t he Rare Earth Socie ty of Japan Award(2006), ACS Award for Creative Work in Synthetic O rganic Chemisty(2008), Centenary medal and lectureship (2008), Pre log Award Medal(2008), and many others.

Direct catalytic asymmetric vinylogous reactions of an α,β-unsaturated γ-butyrolactam as a donor are described. A homodinuclear Ni2-Schiff base complex promoted a vinylogous Mannich-type reaction of N-Boc imines as well as a vinylogous Michael reaction to nitroalkenes selectively at the γ-position under simple proton-transfer conditions. Vinylogous Mannich adducts were obtained in 5:1→30:1 dr and 99% ee, and vinylogous Michael adducts were obtained in 16:1→30:1 dr and 93−99% ee.
