synthesis of the cruciferous phytoalexin (S)-(−)-spirobrassinin and its (±)-2′-amino analogues have been achieved. Our synthetic route towards (S)-(−)-spirobrassinin is based on the CrO3-mediated cyclization of chiral 1-(2′,3′,4′,6′-tetra-O-acetyl-ß-D-glucopyranosyl)brassinin and subsequent removal of the chiral auxiliary. (±)-2′-Amino analogues of spirobrassinin and 1-methoxyspirobrassinin were obtained
