title: Expedient total syntheses of WIN 64745 and WIN 64821.
abstract: Bispyrrolidinoindoline diketopiperazine alkaloids were synthesized from a common intermediate in seven steps from commercially available amino acids. This versatile synthetic strategy has led to the accomplishment of the first total synthesis of heterodimeric WIN 64745 and a novel approach to homodimeric WIN 64821.
