A general methodology for the synthesis of highly substituted butyrolactones in enantiomerically pure form has been developed. The application of this process in a highly efficient synthesis of lactone natural products blastmycinone (1), NFX-2 (2), antimycinone (3), and NFX-4 (4) and two lipid metabolites (5, 6) are described. Additionally, the total synthesis of 5-epi-blastmycinone (22), 5-epi-NFX-2
已经开发出合成对映体纯形式的高度取代的丁内酯的通用方法。描述了该方法在高效合成内酯天然产物blastmycinone(1),NFX-2(2),antimycinone(3)和NFX-4(4)以及两种脂质代谢物(5,6)中的应用。另外,还描述了5-表胚芽孢霉素(22),5-表-NFX-2(21b),5-表-NFX-4(21c)和脂质代谢产物类似物(19、20)的总合成。目标分子的总产率是迄今为止文献中报道的最高。
