A convenient chiron approach to (4R,5R)-5-hydroxyalkylbutan-4-olides and the corresponding 7-oxa analogues from d-(+)-mannitol via an advanced common precursor: syntheses of (−)-muricatacin, 7-oxa-(−)-muricatacin, (4R,5R)-(−)-5-hydroxy-4-decanolide, and (4R,5R)-(−)-7-oxa-5-hydroxy-4-dodecanolide

An efficient and concise chiron approach toward the synthesis of (−)-muricatacin and its unnatural 7-oxa analogue starting from commercially available and inexpensive d-(+)-mannitol via an advanced common chiral precursor has been described. In addition, (4R,5R)-(−)-5-hydroxy-4-decanolide and (4R,5R)-(−)-7-oxa-5-hydroxy-4-dodecanolide were also synthesized to show the versatility of this synthetic
