Ru(CO)-salen-Catalyzed Synthesis of Enantiopure Aziridinyl Ketones and Formal Asymmetric Synthesis of (+)-PD 128907

Aziridination of vinyl ketones using SESN3 in the presence Ru(CO)-salen complex 1 provides the enantiopure aziridinyl ketones that can serve as useful chiral building blocks. A formal asymmetric synthesis of (+)-PD 128907 was achieved in an eight-step sequence via aziridination.
