Synthesis of secasterol and 24-episecasterol and their toxicity for MCF-7 cells
摘要:
The convergent synthesis of biosynthetic precursors of brassinosteroids with a Delta(2)-bond in cycle A-secasterol and 24-episecasterol-was performed. The key stages in the construction of the side chain in these compounds were the Julia olefination of the steroid 22-aldehyde followed by the Sharpless asymmetric dihydroxylation of the intermediate Delta(22)-olefin. The cytotoxicity of the synthesized compounds for breast carcinoma MCF-7 cells was assessed.
