The product is a phosphinooxazoline (PHOX) ligand introduced by Pfaltz and coworkers. These non-symmetrical modular P,N-ligands are particularly useful in cases where double bond migration leads to undesired products or mixtures of isomers.

2021年5月21日 · A key Pd/(S)-tBu-PHOX (1)-catalyzed enantioselective allylic alkylation was employed to synthesize ketone 108, bearing a chloro-substituted allyl moiety and a methyl group at the α-position, in 82% yield and 92% ee.

(S)-tBuPHOX-Pd-MAH is a chiral Pd(0) precatalyst first produced in the group of David C. Leitch for asymmetric allylic alkylation reactions. The complex bears a chiral Pfaltz-Helmchen-Williams (PHOX) ligand as well as an easily diplaced maleic anhydride (MAH) ligand.

DSPP（二琥珀酰亚胺基膦酸，PhoX）和 TBDSPP（叔丁基二琥珀酰亚胺膦酸盐，tBu-PhoX）是可富集膦酸的交联剂，在7原子间隔臂的各端含有胺反应性 N-羟基琥珀酰亚胺 (NHS) 酯，且具有用于富集的膦酸基团 (DSPP) 或膦酸酯 (TBDSPP)。 两者均可在 pH 值为 7–9 的缓冲液中与伯胺基团 (-NH2) 高效反应，以形成稳定的酰胺键。 然后，可使用膦酸或膦酸酯基团通过固定化金属亲和色谱分析 (IMAC) 或金属氧化物亲和色谱分析 (MOAC) 富集交联肽。 在两种可富集的 MS 交联 …

2011年12月7日 · The design relies on the incorporation of geminal substituents at C5 in combination with a substituent at C4 other than t-butyl (i-Pr, i-Bu, or s-Bu). Most of these new members of the PHOX ligand family behave similarly in terms of stereoinduction to t-Bu-PHOX in three palladium-catalyzed asymmetric transformations. Electronically modified ...
