With the newly optimized conditions in hand, the scope with respect to both the phenol nucleophile and the bis-thiazolidinone derived P(V) electrophile was assessed (Scheme 2). Pleasingly, and in contrast to our previously reported method , when using phenyl-substituted P(V) electrophile P1, unsubstituted phenol (1, 75% yield, 99:1 e.r. vs 57% yield, 53:47 e.r. under the firstgeneration conditions), as well as a wide range of electron donating substituents at the phenol para-position were well tolerated, providing desired products (2-4) with high levels of yield and enantioselectivity. When para-fluoro-phenol was employed, 2.0 equivalents of the nucleophile were required to obtain desired product 5 in 48% yield and 93.7 e.r. Most noticeably, nucleophiles bearing additional Lewis basic substituents which could disrupt the non-covalent interactions between the substrate and catalyst were well tolerated, namely products derived from phenols bearing a benzylic ester (6) and a pyridine (7) were obtained in 74% and 53% yield, and 97.5:2.5 e.r. and 92:8 e.r., respectively. Single crystal X-ray diffraction analysis of a suitable crystal of 2 established the absolute configuration of the desymmetrised products as (R).
