An operationally simple and highly atom-economic anionic quadruple domino reaction sequence for the synthesis of hexacyclic indeno-fused naphthalene/quinoline molecules having structural resemblance with the C-nor-D-homo-steroid nucleus has been developed. Promoter and solvent specificity, regioselectivity and mechanistic details were experimentally established. Catalyst concentration and solvent dependent switching of domino steps creating four new C-C bonds are discussed.
Iodine-promoted oxidative conversion of o-vinyl diaryl ketones into o-acetyl diaryl ketones, synthesis of 1-methyl-4-arylphthalazines as analogues of podophyllotoxin

A new method is described for the metal-free oxidation of o-vinyl diaryl ketones in the presence of molecular iodine or N-iodosuccinimide to give o-acetyl diaryl ketones. This transformation involves the initial formation of an iodohydrin, and the o-carbo

Synthesis of multi-branched dipyrromethene dyes with soluble diethynylphenyl links

Multi-branched dyes were prepared using a convergent step-by-step procedure. The key dibutoxydiethynylphenyl spacing units were first linked to a difluoroboradipyrromethene (yellow fluorophore) dye via the pseudo-meso position and then selectively cross-coupled to a di-(4-phenyliodo)ethynylborodiisoindolomethene (red emitter via the boron). When ethynylpyrene units were connected at the periphery to the boron of the yellow emitter, efficient cascade singlet energy transfer events occurred from the pyrene to the yellow and to the red emitters.
Synthesis of 1,2-diacylbenzenes from o-hydroxyaryl ketone acylhydrazones using [(diacetoxy)iodo]benzene

2'-Hydroxyacetophenone and 2'-hydroxypropiophenone acylhydrazones 3 are oxidized to 1,2-diacylbenzenes 4 using [(diacetoxy)iodo]benzene in dichloromethane at room temperature in a synthetically useful and high yield reaction.
