A refreshing cascade: General fluorocyclization reactions will breathe new life into the use of fluorinated hetero‐ and carbocycles as pharmaceuticals and agrochemicals. Allyl silanes have now been shown to undergo fluorination–cyclization with NF reagents to give cis‐ and trans‐substituted fluorinated heterocycles selectively (see scheme). The correct choice of silyl group was critical to prevent
令人耳目一新的层叠:普通的氟环化反应将为氟化杂合和碳环化合物作为药物和农用化学品的使用注入新的活力。现在烯丙基硅烷已显示出经过氟化环有N ˚F试剂给予顺-和反式选择性取代含氟杂环化合物(见方案)。正确选择甲硅烷基对防止竞争性氟代脱甲硅烷基化至关重要。
