## Abstract The ^13^C‐labelled putative erythromycin biosynthetic intermediates, ((2__S__,3__S__,4__S__,5__R__,6__R__,7__R__)‐3,6,7‐trihydroxy‐2,4,6‐trimethyl[1‐^13^C]nonan‐5‐olide and __S__‐2‐acetylaminoethyl (2__R__,3__S__,4__S__,5__R__,6__S__,7__R__)‐3,5,6,7‐tetrahydroxy‐2,4,6‐trimethyl[1‐^13^C]
The title compound, C 12 H 22 N 2 O 6 , is a linearly fused di(trihydroxypiperido)piperazine. The three six-membered rings adopt chair conformations with all the hydroxyl groups equatorial, and the ring fusion is the unusual trans±cisoid±cis.
