On this line, we afforded the synthesis of the bifunctional chiral ligands (R)-1-amminobutan-2-ol and (S)-1-amminobutan-2-ol, (S/R)-CH3CH2CH(OH)CH2NH2 which structure is reported in Figure for the two enantiomers, containing both amino and hydroxyl functional groups, with the chiral carbon being the one bearing the -OH group. For shake of brevity, in the following, the chiral ligands will be defined as "(S-/R-)AMOL", indicating the fact that, from a chemical point of view, such bifunctional molecules are amino alcohols. Their synthesis was carried out starting from epoxides which are readily available versatile building blocks for the synthesis of many structural motifs. These compounds were easily prepared from racemic mixtures and the reactivity towards the regiospecific oxirane ring opening with soft nucleophiles is well known. The two AMOL enantiomers were prepared according to literature procedures starting from the corresponding epoxide. A detailed description of the synthetic procedure is reported in the Supporting Information (SI), together with spectroscopic data, including the optical rotation power. From the steroechmical point of view, the absolute configuration of starting material is the same of amino alcohol obtained following the protocols described in the literature. The two enantiopure AMOL ligands have been used to prepare lead iodide samples by means of solution chemistry as reported in the Experimental Section (see SI). The corresponding powder Xray diffraction (XRD) patterns of the two lead iodide samples including (S-/R-)AMOL are shown in Figure (as sqrt of the intensity to better highlight low-intensity peaks). As expected, the two patterns are similar each other and are characterized by a very intense first peak at low-angle which is typical of layered or low-dimensional perovskites.
