Hauser annulation of 3-cyano-5,7-dimethoxy-(3H)-isobenzofuran-1-one 4 with ethyl acrylate as a method to access activated naphthoquinone 3, a key intermediate for the synthesis of thysanone 1, proved unreliable. In contrast to this, Hauser annulation

The enantiomers of mandelic acid have each been converted into 1,3-dioxolan-4-one derivatives. Formation of the planar chiral (η6-arene)tricarbonylchromium complexes has enabled an investigation of their potential to promote discrimination between t

The photolytic reaction of N-methylbenzylideneimine with 12-methoxypodocarpane chromium carbenes gave products derived either from carbon monoxide dissociation followed by 12-methoxy ligation or from oxidation of the carbene metal moiety, while the r

The insertion of alkyl- or aryl-substituted alkynes into chromium aminocarbenes derived from podocarpic acid gives good to excellent yields of cyclopentaannulated products. The presence of a heteroatom bonded directly to the alkyne lowers the yield o

Insertion reactions of electron-deficient alkenes with chromium aminocarbenes derived from podocarpic acid generally give aryl ketone products derived from ring opening of an aminocyclopropane and subsequent enamine hydrolysis, the exception being al

Chromium aminocarbene complexes of podocarpane diterpenoids have been synthesised in good to excellent yields, either by aminolysis of the corresponding alkoxycarbene, or by treatment of the morpholino amide with disodium pentacarbonylchromium and su

Ortho -(2-triethoxysilylethyl) derivatives of aryl ketones undergo oxidative desilylation with H 2 O 2 . Tetralone derivatives have served as model substrates for 14-2-(triethoxysilylethyl)-7-oxopodocarpanes, which have been converted into 2-aryletha

Vinyl trialkylsilanes are efficient substrates for use in the ortho alkylation of aromatic ketones catalysed by zerovalent ruthenium complexes, giving, e.g. (2-trimethylsilylethyl)acetophenones. Methods for the selective desilylation–functionalisat
