Bidirectional syntheses of C2-symmetrical lipids embedding two terminal alkynylcarbinol pharmacophores are reported. Naturally occurring chiral alkenylalkynylcarbinol units were generated using Pu’s procedure for enantioselective addition of terminal alkynes to aldehydes, allowing the first asymmetric synthesis of (3R,4E,16E,18R)-icosa-4,16-diene-1,19-diyne-3,18-diol, isolated from Callyspongia pseudoreticulata
报道了嵌入两个末端炔基咔啉药效基团的C 2对称脂质的双向合成。天然存在的手性链烯基炔基甲醇单元是使用Pu程序生成的,用于将末端炔烃对映体选择性加成醛,从而首次合成(3 R,4 E,16 E,18 R)-icosa-4,16-diene-1,19 -diyne-3,18-diol,从拟南芥中分离。嵌入最近发现的两个合成类似物(S)-二炔基卡宾醇药效团使用适用于ynal底物的Carreira方法固定。通过针对HCT116细胞的亚微摩尔IC 50值,证实了甲醇构型对细胞毒性的显着影响。
