Hirokawa, Yoshimi; Kitamura, Maria; Maezaki, Naoyoshi published the artcile< Highly enantioselective [2,3]-Wittig rearrangement of functionalized allyl benzyl ethers: a novel approach to lignan synthesis>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is enantioselective Wittig rearrangement allyl benzyl ether.
Highly enantioselective [2,3]-Wittig rearrangement of functionalized allyl benzyl ethers (E)-ArCH2OCH2C(OSi-iPr3):CHMe [Ar = Ph, 4-MeOC6H4, 3,5-(MeO)2C6H3, etc.] was accomplished using a chiral di-tert-Bu bis(oxazoline) ligand. The reaction proceeded with excellent diastereo- and enantioselectivity when no methoxy substituent was present at the ortho-position on the benzyl group. On the other hand, the enantioselectivity was drastically decreased in the presence of an ortho-methoxy group.
