二最近识别的自然酉分的 homobenzyl 酉旨,从 Phragmipedium 孤立 calurum (一朵兰花) 和 Eupatorium fortunei TURCZ (在 Asteraceae 家庭的长期的植物) 分别地,在 enantiopure 形式被综合。由光旋转为的比较合成并且自然样品,为自然产品的绝对配置可靠地被分配。合成也启用密切相关的自然 homobenzyl 白酒的绝对配置的建立并且为二另外的自然 homobenzyl 酉旨为第一次提供了完全的物理、分光镜的数据。
Two recently identified natural phenolic homobenzyl esters, isolated from Phragmipedium calurum (an orchid) and Eupatoriumfortunei TURCZ (a perennial herb in the Asteraceae family), respectively, were synthesized in enantiopure forms. By comparison of the optical rotations for the synthetic and the natural samples, the absolute configurations for the natural products were reliably assigned. The synthesis also enables establishment of the absolute configuration of a closely related natural homobenzyl alcohol and provided for the first time complete physical and spectroscopic data for two other natural homobenzyl esters.
