The effect of solvent on oxidative cleavage of the Hajos–Parrish ketone derived hydrindene–diols 1 , and Wieland–Miescher ketone derived octaline–diols 2 with Pb(OAc) 4 is presented. Various solvents were screened and compared for these domin

Carvone derived octaline diols 1 and 2 were subjected to Pb(OAc)4-mediated glycol fission conditions. The isolable ‘half-cascade’ intermediate 3 was subjected to ozonolysis in methylene chloride, and subsequent basic treatment, providing bis-angu

We report the oxidative cleavage of unsaturated diols 6 and 7 derived from monocyclic precursors, used as substrates to determine the limits of the olefin as a source of diversity.

Treatment of a series of unsaturated diols with iodobenzene diacetate (PhI(OAc) 2 ), in various solvents gave cyclic ene-acetals by a sequential oxidative cleavage-intramolecular [4+2] cycloaddition. The reaction is easy to perform, can be scaled up

The Mn(OAc)3 mediated oxidative cleavage of 1 and 2 proceeded as expected, while molecular diversity was generated upon cleavage of their unsaturated counterparts 5 and 6 via a tandem glycol cleavage/4+2 process. Minor products of the reaction were i

A new method for the direct conversion of oximes into aldehydes and ketones by treatment with manganese triacetate is described. Manganese triacetate can be used for an effective and mild oxidizing agent for the regeneration of carbonyl compounds fro
