  17. Depending on the scale different separation procedures were applied. Typically on >2 g scale either3 aor5 awas selectively crystallized from the mixture (see Supporting Information for details) and the residue was purified by flash chromatography. On a smaller scale the diastereomers were separated by flash chromatography; for example 1.21 g of a mixture of3 a/3 bwas separated by flash chromatography to give3 a(595 mg) and3 b(501 mg; 91 % mass recovery).
