Gram-Scale Synthesis of the C14–C23 Fragment of Eribulin

open access: yesOrganic Process Research and Development, 2023
Eribulin is a structurally simplified and completely synthetic analogue of macrocyclic ketone halichondrin B. In 2010, eribulin was approved by FDA for the treatment of metastatic breast cancer (MBC).

Synthesis of the C9−C23 (C9′−C23′) Fragment of the Dimeric Natural Product Rhizopodin

Organic Letters, 2010
A stereoselective assembly of the C9-C23 (C9'-C23') fragment of rhizopodin, a 38-membered bis-lactone natural product, has been developed. A highly efficient approach to this fragment assembles >50% of the carbon skeleton and the stereochemical elements present in the natural product.

Immunodominant RNA recognition motifs of human nucleolin/C23

Molecular Immunology, 1995
Nucleolin/C23 is a nucleolar phosphoprotein implicated in the synthesis, processing and transport of ribosomal RNA and gene transcription. Auto-antibodies to human nucleolin/C23 have been reported in patients with systemic lupus erythematosus and other systemic autoimmune disorders.

Chemoenzymatic Synthesis of the C10−C23 Segment of Dictyostatin

Organic Letters, 2006
[reaction: see text] Employing enzymatic desymmetrization and resolution, respectively, the two aldehydes 8 and 20 were prepared. The precursor to aldehyde 8, meso-2,4-dimethylglutaric anhydride 3, could be obtained by base treatment of the diastereomeric mixture. Aldehyde 8 was extended to alkyne 10 by a Marshall reaction introducing four carbon atoms.
