ETUDES DE LIGNANES 7 - SYNTHESES TOTALES DES (+-)-α ET -β-CONIDENDRINES ET DES METHYL (+-)-α ET -β-CONIDENDRALS

Michael addition of the carbanion of the dithian 8 on butenolide, followed by alkylation with the benzylic bromide 11 and regeneration of the ketonic carbonyl group, gave the α,β-disubstituted lactone 13.Reduction of the ketonic carbonyl of the latter usi

(+)-TSUGACETAL, A LIGNAN ACETAL FROM TAIWAN HEMLOCK

Key Word Index - Tsuga chinensis var. formosana; Taiwan hemlock; lignan acetal; tsugacetal; X-ray crystal structure. - By the evidence of (1)H and (13)C NMR spectra, and single crystal structure determination, a novel lignan acetal, (+)-tsugacetal, isolated from Tsuga chinensis var. formosana, was found to have an α-conidendrin-related structure with an acetal methoxy group at the β-position.
