Six conformationally restricted carba-sugars have been synthesized by ring-closing metathesis of a readily available diallyl keto derivative of (–)-quinic acid. The rich functionality of the resulting spiro ketone was exploited for the diastereoselective synthesis of various spiro carba-sugars: four of them polyhydroxylated and two aminopolyhydroxylated. The results of the testing of these compounds
六种构象受限的碳水化合物已通过 (-)-奎尼酸的现成二烯丙基酮衍生物的闭环复分解合成。所得螺酮的丰富功能被用于各种螺卡巴糖的非对映选择性合成:其中四种多羟基化和两种氨基多羟基化。提供了针对各种市售糖苷酶(淀粉糖苷酶、α-和β-半乳糖苷酶、α-和β-葡萄糖苷酶、α-甘露糖苷酶、海藻糖酶和神经氨酸酶)的这些化合物的测试结果。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
