In vitro inhibition of food spoilage and foodborne pathogenic bacteria by essential oil and leaf extracts of Magnolia liliflora Desr.
TL;DR: The results obtained in this study support the role of essential oil and the leaf extracts derived from M. liliflora as a remarkable approach to inhibit the growth of food spoilage and foodborne pathogens.

Rearranged prenylated C6-C3 compounds and a highly oxygenated seco-prezizaane-type sesquiterpene from the stem bark of Illicium oligandrum.
TL;DR: Three new rearranged prenylated C(6)-C(3) compounds, named illioliganones A, B, and C (1-3), and a new highly oxygenated seco-prezizaane-type sesquiterpene, oligandriortholactone (7), together with three known prenylon compounds (4-6), have been isolated from the stem bark of Illicium oligandrum.

Catalyst-free synthesis of 2,3-dihydrobenzofurans through [4+1] cycloaddition of ortho-hydroxyphenylsubstituted para-quinone methides and sulfur ylides
TL;DR: In this article, an efficient cycloaddition of ortho-hydroxyphenylsubstituted para-quinone methides and sulfur ylides was achieved under the catalyst-free condition.
Journal ArticleDOI
Construction of bicyclo[3.2.1]octanes with four stereogenic centers by organocatalytic domino Michael/Aldol reaction.
TL;DR: An enantio- and diastereoselective organocatalytic domino Michael/Aldol reaction for the direct preparation of synthetically and medicinally relevant bicyclo[3.2.1]octane derivatives with four stereogenic centers, including two quaternary carbons, has been described.

Neolignans from a Nectandra species
TL;DR: The trunk wood of an Amazonian Nectandra (Lauraceae) species contains one bicyclo[3.2.1]octanoid and four hydrobenzofuranoid neolignans, a new representative of the seemingly rare macrophyllin type.

Bicyclo[3,2,1]octanoid, neolignans from Aniba simulans
TL;DR: In this paper, six bicyclo[3,2,1]octanoid neolignans, isolated from the benzene extract of Aniba simulans Allen (Lauraceae) trunk wood, are shown to derive from two basic structures: 1-allyl-8-hydroxy-6-(3′-methoxy-4′,5′-methylenedioxyphenyl)-7-methyl-3-oxobicyclo [3, 2, 1]octane, substituted by 4-hydrox, 4-oxy-5-
