A New Synthesis of α-Tocopherol
Olson, Gary L.,Cheung, Ho-Chuen,Morgan, Keith,Saucy, Gabriel
, p. 803 - 805 (2007/10/02)
α-Tocopherol (vitamin E,1) has been synthesized in racemic form following a new strategy in which the aromatic ring of the chroman is constructed by addition of the dianion of 2,4-pentanedione to 1,2-epoxy-2,6,10,14-tetramethylpentadecane (5) as a side-ch
