BengamideE (1a) and C-2 epimer (1b), free hydroxyl analogs (1c) and (1d), and shorter chain analog (1e) were synthesized by utilizing (2R,3S,4R)-2,3,4-tris(benzyloxy)hex-5-enal (2a) as the chiral building block. Preliminary biological studies revealed that only compound 1c showed slightly weaker activity than BengamideE (1a) against MDA-MB-453 human breast carcinoma cells, MCF-7 human breast cancer
