In the X-ray crystal of 64, the TBDMS group was best modelled as disordered over two sites in the ratio 0.62:0.38 and only the major conformer is shown. The O-benzyl and 4-benzyl-5,5-dimethyloxazolidin-2-one fragments of the structure also contain some disorder which is reflected in the prolated ADPs for the atoms contained within these fragments
