Asymmetric synthesis of 5,7-O-dimethyleucomols via enantioselective oxidation of enol phosphates

“…2,127.4,128.4 (CAr,CHAr), 132.9 (CH 2 @C), 136.6 (CHAr), 151. 4,158.2,160.4 (CAr), 162.8 (COO); MS (CI, isobutane) 327 (M + , 100).…”

“…1a Since that time other compounds belonging to flavones, isoflavones as well as homoisoflavones have been isolated from various plants. 1b-h Due to their biological properties, for example, (E)-3-(4-methoxy)-3-benzylidene-6-methoxy-chroman-4-one exhibits antifungal activity, 2 some of its substituted derivatives display anti-inflammatory, analgesic, platelet anti-aggregating, 3 and hypo-cholesterolemic activites; 4 3-benzylchromones possess angioprotective, antiallergic, and antihistaminic properties; 5 these derivatives are of great interest to biochemists and organic chemists. The syntheses of these compounds have been an important aim in chemical studies.…”

A short synthesis of 7-amino alkoxy homoisoflavonoides

“…3 To date, a wide range of biological behaviors of homoiso-avonoids, their synthesis and biosynthesis have been studied and reported in the literature. 1,4 These types of compounds have shown many biological activities such as antiangiogenic, 5 antifungal, 6 hypocholesterolemic, 7 antimutagenic, 8 anti-inammatory, 9 and antiviral activities. 10,11 Among natural products containing homoisoavonoid scaffold, Bonducellin (isolated from Caesalpinia bonducella and Caesalpinia pulcherrima) 12 acts as inhibitor of multidrug resistance efflux pump.…”
