A novel route to simple 6,5-benzannulated spiroketal analogues has been developed. A convergent Horner–Wadsworth–Emmons olefination enabled ready assembly of the spiroketal precursors. Use of a benzyl protecting group strategy enabled an efficient one-pot hydrogenation/deprotection/spiroketalisation process to be employed providing a robust method to access a range of substituted aromatic monobenzannulated
已经开发了一种简单的 6,5-benzannulated spiroketal 类似物的新途径。收敛的 Horner-Wadsworth-Emmons 烯化使螺酮前体的组装变得容易。苄基保护基策略的使用使得能够采用高效的单锅加氢/脱保护/螺缩酮工艺,提供了一种可靠的方法来获得一系列取代的芳香族单苄基化螺缩酮。
