2′-Spirobiindan-1,1′-diol (1) was resolved as its (−)-ω-camphanic ester and the absolute rotation of the glycol 1 was determined. Two crown ethers and the acyclic analog were derived from (+)-1. Two crown ethers incorporating (+)-cis,trans-2,2′-spirobiindan-1,1′-diol were also prepared. Their chiral recognition properties in transport of methyl (±)-phenylglycinate hydrochloride and abilities to extract alkali metal
trans,trans-2,2'-Spirobiindan-1,1'-diol (1) 被解析为它的 (-)-ω-camphanic 酯,并确定了乙二醇 1 的绝对旋光度。两种冠醚和无环类似物源自 (+)-1。还制备了两种包含 (+)-cis,trans-2,2'-spirobiindan-1,1'-diol 的冠醚。研究了它们在运输甲基(±)-苯基甘氨酸盐酸盐中的手性识别特性和提取碱金属苦味酸盐的能力。
