This work reports rhodium catalyzed selectivehydroformylation of natural olefins like eugenol, estragole, anethole, prenol and isoprenol using biphenyl based Buchwald phosphine ligands (S‐Phos (L1), t‐Bu XPhos (L2), Ru‐Phos (L3), Johnphos (L4) and DavePhos (L5). Ru‐Phos (L3) ligand exhibited high impact on the hydroformylation of eugenol providing high selectivity (90%) of linear aldehyde as major product

hydroformylation of allylicalcohols is reported toward the synthesis of β-hydroxy-acid and aldehyde products. The selectivity is achieved through the use of a ligand that reversibly binds to alcohols in situ, allowing for a directed hydroformylation to occur. The application to trisubstituted olefins was also demonstrated, which yields a single diastereomer product consistent with a stereospecific addition of CO
据报道,烯丙醇的高度区域选择性加氢甲酰化可用于合成 β-羟基酸和醛产物。选择性是通过使用一种配体来实现的,该配体在原位可逆地结合醇,允许发生定向加氢甲酰化。还证明了三取代烯烃的应用,这产生了与 CO 和氢的立体有择加成一致的单一非对映异构体产品。
