The wrong enantiomers of (−)-gabosine H (5), (−)-epi-gabosine H (epi-5) and intermediates 6–10, 11a,b, and 12–22 were drawn in the Abstract, Table of Contents, and Schemes 2–6. The correct structural drawings for these compounds are provided. The corrected Abstract and Table of Contents graphic is shown: Corrected Schemes 2–6 are shown: In ref 4, we inadvertently overlooked a pertinent review: (c)

the interaction of threose 4-phosphate and 2-deoxyerythrose 4-phosphate with 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase (DAH7PS) reveals previously unrecognised mechanistic differences between the DAH7PS-catalysed reaction and that catalysed by the closely related enzyme, 3-deoxy-D-manno-octulosonate 8-phosphate synthase (KDO8PS).

Practical syntheses of trans-dihydroxybutyrolactols 2a, 2b and 2c from inexpensive chiral pool compounds L-ascorbic, D- and L-tartaric acid have been achieved on a multigram-scale. The synthetic applications of these chiral building blocks have been demonstrated in the efficient total or formal synthesis of polyhydroxylated alkaloids (+)-lentiginosine and (−)-deacetylanisomycin in concise routes.
