Syntheses of 2-Substituted 6/7-Methoxy-1,4-benzodioxan-7/6-carbaldehydes

Five 2-substituted 6/7-methoxy-1,4-benzodioxan-7/6-carbaldehydes and 6-methoxy-1,4-benzodioxan-7-carbaldehyde available for the syntheses of insecticidal neolignan analogs were prepared from 4/3-benzyloxy-3/4-hydroxybenzaldehydes and 1,4-benzodioxan-6-carbaldehyde, respectively.

Synthese et proprietes biologiques photoinduites de dioxinnocoumarines lineaires

Synthesis and photoinduced biological properties of linear dioxinocoumarins.Several dioxinocoumarins with a substituted or unsubstituted coumarin moiety were synthesized from commercially available 6-amino-1,4-benzodioxan.Qualitative assays on the photoinduced inhibition of growth in the yeast Saccharomyces cerevisiae indicate that two dioxinocoumarins are photobiologically active. The 5H- benzopyranobenzodioxin-5-one 1d is more active than angelicin but less active than 8-MOP.The 9-methyl-7H-pyranobenzodioxin-7-one 1c is slightly less active than angelicin.
