The first synthesis of [26,27-2H6]24-epi-cathasterone 8via (20S)-3β-acetoxy-6,6-(ethylenedioxy)-20-formyl-5α-pregnane 5 starting from stigmasterol is described. The aldehyde 5 was alkylated with lithium butyldimethyl-(E)-2,3-dimethyl[3,3,3,4,4,4-2H6]butenylaluminate 6 prepared from 3-[2H3]methyl[4,4,4-2H3]but-1-yne. The structure was determined using spectral data and X-ray crystallographic analysis.
本论文描述了首次通过(20S)-3β-乙酰氧基-6,6-(亚乙二氧基)-20-甲酰基-5α-孕甾烷 5 从赤霉醇合成 [26,27-2H6]24-epi-cathasterone 8。醛 5 与由 3-[2H3]甲基[4,4,4-2H3]丁-1-炔制备的丁基二甲基-(E)-2,3-二甲基[3,3,3,4,4,4-2H6]丁烯铝酸锂 6 进行烷基化。通过光谱数据和 X 射线晶体分析确定了其结构。
