50 - 178Total Syntheses of Neuroprotective Mastigophorenes A and B. —The synthesis of precursor (VII) is achieved via enantioselective formation ofester (III) and intramolecular Heck reaction of iodide (IV). Horseradish per-oxidase mediated dimerization of (IV) gives a 1:2 mixture of the atropisomersmastigophorenes A and B. Both compounds exhibit significant neuroprotectiveactivity in primary cultures of fetal rat cortical neurons. — (FUKUYAMA,YOSHIYASU; MATSUMOTO, KEIJI; TONOI, YASUTOSHI; YOKOYAMA,RITSUKO; TAKAHASHI, HIRONOBU; MINAMI, HIROYUKI; OKAZAKI,HIROSHI; MITSUMOTO, YASUHIDE; Tetrahedron 57 (2001) 33, 7127-7135;Fac.
