Copper-Catalyzed Ring Opening of Benzofurans and an Enantioselective Hydroamination Cascade
Xu-Xu, Qing-Feng,Liu, Qiang-Qiang,Zhang, Xiao,You, Shu-Li
, p. 15204 - 15208 (2018)
A copper(II) acetate/(R)-DTBM-SEGPHOS-catalyzed ring opening of benzofurans and enantioselective hydroamination cascade with dimethoxymethylsilane (DMMS) and hydroxylamine esters is described. Starting from readily available substituted benzofurans, a series of chiral N,N-dibenzylaminophenols, which are of high interest in pharmaceutical chemistry, were obtained with excellent enantioselectivities (up to 66 % yield, 94 % ee).
PREPARATION AND CYCLIZATION OF ARYLOXYACETALDEHYDE ACETALS; A GENERAL SYNTHESIS OF 2,3-UNSUBSTITUTED BENZOFURANS
Barker, Peter,Finke, Paul,Thompson, Kevan
, p. 257 - 266 (2007/10/02)
A improved method for the preparation of 2,3-unsubstituted benzofurans is described.Specifically, the PPA catalysed cyclization of aryloxyacetaldehyde acetals to give (4-7)-substituted benzofurans has been achieved.
