Vinyl Expoxide Tsuji Trost

Palladium catalyzed cross coupling of vinyl epoxides and aziridines with organoboronic acids was performed by using 0 5 2 5 mol pincer complex catalyst. Subsequently a retro claisen condensation is utilized as a means of through space anion relay. Trost reaction 22 vinyl epoxides have been employed previously in palla dium catalyzed allylations 23 but to the best of our knowl edge reports using anickel based catalyst a nonprecious inexpensive catalyst are scarce 24 with only afew examples being reported involving cycloaddition reactions atthe.
