  Syntheses and Biological Activity Studies of Novel Sterol Analogs from Nitroso Diels−Alder Reactions of Ergosterol

  摘要：

  A series of novel sterol analogs was prepared using nitroso Diels-Alder reactions with ergosterol. Most cycloaddition reactions proceeded in an excellent regio- and stereoselective fashion. Further N-O bond cleavage of cycloadducts generated compounds with biological activity in PC-3 and MCF-7 cancer cell lines.
