Rh(III)-catalyzed cascade C-H activation of benzoylacetonitriles and annulation with sulfoxonium ylides was realized, leading to selective synthesis of naphthols, 2,3-dihydronaphtho[1,8- bc]pyrans, and naphtho[1,8- bc]pyrans. This step-economic reaction proceeded efficiently under mild and redox-neutral conditions via multiple C-H activations.
铑（III）催化的苯甲酰乙腈的级联 C-H 活化与亚砜叶立德的环化反应得到了实现，从而选择性地合成了萘酚、2,3-二氢萘并[1,8-bc]吡喃和萘并[1,8-bc]吡喃。该步经济性反应在温和和氧化还原中性条件下通过多次 C-H 活化高效进行。
