(Figure Presented) It's a trap: The photochemical homolytic cleavage of an α-diketone leading to degradation products was suppressed through the encapsulation of the diketone in a self-assembled cage. Instead, intramolecular cyclization products were formed through otherwise unfavorable (kinetically hidden) reaction pathways. This provides an approach to find new reactions of photolabile compounds that had been abandoned because of predominant cleavage reactions.

The synthesis of 2-arylcoumaranones and 2-phenyllbenzofuran has been achieved in good yields under acid catalysed conditions from readily accessible and suitably substituted aryl α-diazo-arylmethyl ketones.
Unusual behaviour of diethylbromomalonate with 2-hydroxydesoxybenzoins. Convenient synthesis of 2-aryl-3(2H)-benzofuranones

Formation of 2-aryl-3(2H) benzofuranones in the reaction of diethylbromomalonate with 2-hydroxydesoxybenzoins is reported along with their further conversion into 2-arylbenzofurans.

Solvolytic rearrangement of tosylates of 3-alkyl(aryl)-benzofuryl-2-alkyl ketoximes and 2-substituted(and unsubstituted)benzofuryl-3-methyl ketoximes with aqueous methanol depends upon their configurations.The tosylates of 2-ethyl(benzyl)benzofuryl-3-methyl ketoximes obtained in alkaline medium do not undergo solvolytic rearrangement under similar conditions.The isomerisation of anti-isomers of the above mentioned ketoximes to syn-forms with hydrogen chloride is unsuccesful.The configurations of syn- and anti-isomers of benzofuryl-2-alkyl(aryl) ketoximes have been studied by PMR spectroscopy.
