• Benzo[<i>f</i>][1,2]oxasilepines in the Synthesis of Dihydro[<i>b</i>]benzofuran Neolignans
  作者：Ignacio Rodríguez-García、Sergio García-Muñoz、Leticia Jiménez-González、Míriam Álvarez-Corral、Manuel Muñoz-Dorado

  DOI：10.1055/s-2005-921913

  日期：——

  A short synthesis of neolignans with a dihydrobenzo[b]furan skeleton is described. The strategy is based on a ring-closing metathesis to produce benzo[f][1,2]oxasilepines which are condensed with aromatic aldehydes in a modified Sakurai-Hosomi reaction. Natural dihydrodehydrodiconiferyl alcohol (1) and 3-0-demethyldihydrodehydrodiconiferyl alcohol (2) have been prepared in this way.

  日期：——

  Structural revision of lawsonicin, a natural product of Lawsonia alba, is reported based upon comparison of its spectral data with that of the naturally occurring dihydrobenzo[b]furan neolignan (rac)-trans-dihydrodehydrodiconiferyl alcohol, which is found to be identical. A concise synthesis of dihydrodehydrodiconiferyl alcohol, via Rh2[S-DOSP]4-catalysed intramolecular C–H insertion, is described.

  Six new dihydrobenzofuran lignans, named illiciumlignans A⿿F (compounds 1⿿6), along with 15 known compounds (7⿿21) were isolated from the branches and leaves of Illicium wardii. The structures of 1⿿6 were determined using a combination of 1D and 2D NMR, HR-ESI⿿-MS, and CD spectroscopic data. Illiciumlignan D (4) is the first reported dihydrobenzofuran lignan arabinofuranoside that is derivatized with
