Air-stable and tunable chiral bisdihydrobenzooxaphosphole ligands (BIBOPs) were employed in rhodium-catalyzed asymmetric hydroformylation of various terminal olefins with excellent conversions (>99%), moderate-to-excellent enantioselectivities (up to 95:5 er), and branched to linear ratios (b:l) of up to 400.

You′re having a lahf! The asymmetrichydroformylation (AHF) of allylic compounds, catalyzed by a rhodium–yanphos complex, is a direct and concise route to β2‐amino aldehydes, acids, and alcohols with excellent enantioselectivity (see scheme; TON=turnover number, acac=acetylacetonate).
你在做饭!的不对称加氢甲酰基烯丙基化合物(AHF),由铑- yanphos配合物催化,是对β的直接和简明路线2 -氨基醛,酸,和具有优异的对映选择性醇(参见方案; TON =周转数,ACAC =乙酰)。
