Bio-inspired dimerisation of prenylated quinones directed towards the synthesis of the meroterpenoid natural products, the scabellones

Stirring 2-geranyl-6-methoxy-1,4-hydroquinone in pyridine/O2 or 2-geranyl-6-methoxy-1,4-benzoquinone in pyridine/N2 affords the dimeric meroterpenoid natural products, scabellones A-C in modest to low yields and also identifies 2-methoxy-6-(4-methylpent-3-en-1-yl)-1,4-naphthoquinone (scabellone E) as a new natural product. The corresponding reaction of the des-methoxy analogue, 2-geranyl-1,4-benzoquinone in degassed pyridine for three days afforded the natural product cordiachromene A (15% yield) and 6-(4-methylpent-3-en-1-yl)-1,4-naphthoquinone (12%), the latter being a likely biosynthetic precursor to the marine meroterpenoid alkaloids, conicaquinones A and B.

Efficient access to (All-rac)-α-Tocopherol acetate by a crombie chromene synthesis

In contrast to reports in the literature, the pyridine-catalysed condensation of phenolic compounds and conjugated aldehydes to chromenes was found to be applicable to trimethylhydroquinone 2a with the result of complementary convergent approaches to the

Synthesis of various 2H-benzopyran compounds and their kinetic resolution by asymmetric hydrolysis of their racemic acetates mediated by lipases

The preparation of 2H-benzopyrans from bromophenols and tertiary allylic alcohols is described. The reaction is characterised by its mildness, good yields and ease of work-up. Kinetic resolution of the latter up to 95% ee was obtained by using enzyme-cata

A short synthesis of cordiachromene

Cordiachromene was synthesized from 5-methyl hept-5-en-2-one by using a Claisen rearrangement.

Synthesis of 2,2-Dimethyl-2H-chromenes via a Palladium(II) Catalysed Reaction

The antijuvenile hormones Precocene-1, Precocene-II and other bioactive 2,2-dimethyl-2H-chromenes have been synthesised by intramolecular oxidative cyclisation of 2-isoprenyl phenols catalysed by a palladium(II) salt.
