Formal syntheses of (±)-mesembrine and (±)-dihydromaritidine

Condensation of 3-arylated Δ1-pyrrolinium salts with t-butyl 3-oxopent-4-enoate 3 followed by treatment with trifluoroacetic acid yielded the alkaloid Δ7-mesembrenone 1 and its N-benzyl analogue 10. These compounds are intermediates

Synthesis of Sceletium and Amaryllidaceae Alkaloids, (+/-)-Mesembrine and (+/-)-Dihydromaritidine, (+/-)-Epidihydromaritidine, (+/-)-Elwesine, and (+/-)-Epielwesine

The alkylation of 2-arylcyclohexanones (12b and 6) with alkyl halides or acrylonitrile and 50percent aq. sodium hydroxide in the presence of a phase-transfer catalyst (18-crown-6) was found to give readily 2-alkyl-2-arylcyclohexanones (14 and 16) in fair
