Yttrium triflate as an efficient and useful catalyst for chemoselective protection of carbonyl compounds

Carbonyl compounds have been successfully converted into their corresponding oxathiolane, dithiolane, and dithiane derivatives with 2-mercaptoethanol, 1,2-ethanedithiol, and 1,3-propanedithiol using catalytic amount of yttrium triflate. In addition, by us

Biosynthesis. Part 30.1 Colchicine: Studies on the ring expansion step focusing on the fate of the hydrogens at C-4 of autumnaline

Autumnaline 1 is a key biosynthetic precursor of colchicine 4. Syntheses are described of autumnalines that are labelled stereospecifically with tritium at C-4 of their isoquinoline ring. This corresponds to C-12 of the later intermediate dienone 2. Incor

Synthesis of dibenzylbutyrolactone lignans: Total synthesis of arctigenin, pluviatolide and haplomyrfolin by tandem conjugate addition

The total synthesis of three dibenzylbutyrolactone lignans, arctigenin, pluviatolide and haplomyrfolin has been carried out by tandem cnjugate addition of dithiane carbanions to but-2-en-4-olide and substituted benzyl bromides leading to the formation of key intermediates which subsequently underwent debenzylation and desulphurisation.

SYNTHESE TOTALE DE LA (d,l) α-CONIDENDRINE

Michael addition of the carbanion of the dithian 7 (derived from O-benzylvanillin) on butenolide, afforded the saturated lactone 8.Alkylation of the latter with the benzylic bromide 6, followed by regeneration of the carbonyl group gave the α,β-disubstituted lactone 10.Reduction of the ketonic carbonyl group of compound 10 using NaBH4, followed by treatment with CF3CO2H and catalytic hydrogenolysis afforded (d,l)α-conidendrin 1.
