NEOLIGNANS FROM MAGNOLIA KACHIRACHIRAI

Two new neolignans named kachirachirol-A and B were isolated from the leaves of Magnolia kachirachirai and their chemical structures determined to be 2-(p-hydroxyphenyl)-7-methoxy-3-methyl-5-trans-propenylbenzofuran and rel-(2S,3S)-2-catechyl-2,3-dihydro-7-methoxy-3-methyl-5-trans-propenylbenzofuran.Key Word Index - Magnolia kachirachirai; Magnoliaceae; neolignan; benzofuranoid; kachirachirol-A; kachirachirol-B; licarin-A; eupomatenoid.

Cerium ammonium nitrate-mediated the oxidative dimerization of p-alkenylphenols: A new synthesis of substituted (±)-trans- dihydrobenzofurans

A new method for the preparation of substituted dihydrobenzofurans is described. The p-alkenylphenols, mediated by cerium ammonium nitrate (CAN), undergo the oxidative dimerization to generate substituted dihydrobenzofurans including (±)-conocarpan, (±)-licarin A, (±)-acuminatin, as well as their related substituted dihydrobenzofurans.

Synthesis of (±)-licarin B and eupomatenoids-1 and -12: A general approach to 2-aryl-7-alkoxy-benzofuranoid neolignans

New synthesis of the title compounds are described using Lewis acid-promoted reactions of styrenes with N-phenylsulfonyl-1,4-benzoquinone monoimines to regioselectively form the 2-arylbenzofuranoid ring system followed by conversion of the aromatic N-phenylsulfonyl moiety into a propenyl substituent.
