With the N-acyl-glutarimide substrate scope inspected, the cyclopropanol side is then explored by coupling with 1a (Scheme 3). The deletion of OMe from 2d (H, 2a) promotes the reaction to a 79% yield. With 2a as the parent skeleton, a broad range of substituents are tolerated at the para site. The electron-donating Me (2b, 62%) and Cy (2c, 68%) groups lowers the reactivity in reference to the 2a benchmark. For the electron-withdrawing substituents, whereas the F group (2e, 77%) secures a similar reactivity, the Cl group (2f, 53%) apparently exerts a negative impact; the CO2Me substitution (2g, 80%) manages to maintain a superior reactivity; the reactivity drops, only to a small extent, with the strong electron-withdrawing groups of CF3 (2h, 73%) and NO2 (2i, 74%). The ortho site substitution results in an appreciable loss of the reactivity (OMe, 2j, 52%; F, 2k, 48%). The reactivity with the meta substitution (OMe, 2l, 60%; F, 2m, 73%) stands at the intermediate level between that of the para and ortho analog. Not surprisingly, the meta, meta disubstitution (2n, 65%) is compatible with the reaction. The 2-substitution at the cyclopropanol ring of 2a can create a structurally congested environment. Satisfactorily, the 2-Me (2o, 44%) and 2,2-Me (2p, 70%) groups, as well as the spiro Cy moiety (2q, 47%), pose no severe hurdle for the reaction.
