nucleophile was developed. The reaction utilizes inexpensive and readily available (CH3CN)3W(CO)3 as a precatalyst and proceeds at 60 °C temperature in the presence of 2,2′-bipyridine and its derivatives as ligand. The synthetic utility of allylic sulfones as electrophile was further demonstrated through Suzuki–Miyaura cross-coupling as showcased by the formal synthesis of (±)-hinokiresinol.
开发了钨催化的亚磺酸钠作为杂原子亲核试剂的烯丙基烯丙基化。该反应利用廉价且容易获得的(CH 3 CN)3 W(CO)3作为预催化剂,并在2,2'-联吡啶及其衍生物作为配体的存在下于60°C进行。(±)-hinokiresinol的正式合成表明,通过Suzuki-Miyaura交叉偶联进一步证明了烯丙基砜作为亲电试剂的合成效用。
