An enantioselective synthesis of the chiral bisnaphthopyrone natural product nigerone and its enantiomer, ent-nigerone, has been realized. The use of constrained 2-naphthol substrates was critical to producing highly functionalized chiral 1,1′-bina

[reaction: see text] An enantioselective synthesis of the chiral bisnaphthopyrone natural product nigerone is reported. The key step was an eight-step isomerization process to form the final natural product. The isomerization precursor was constructe

This paper describes the synthesis of hexa(ethylene glycol) and carboxymethylhexa(ethylene glycol)-terminated alkane-disulfides 4 and 7, respectively, in which the alkylene chains are twenty-methylenes-long. The key twenty-carbon synthon, 20-bromoico
