Synthesis and reactivity of substituted α-carbonylphosphonites and their derivatives

Convenient methods for the synthesis of functionalized organophosphorus compounds containing carbonyl groups as well as di- or trialkoxymethyl fragments attached to phosphorus, and their derivatives, starting from the available derivatives of trivalent phosphorus acids, are proposed, and some properties of the new functionalized organophosphorus compounds are presented. So, the alkylation and acylation reaction of (dialkoxymethyl) phosphonites and their analogs have been studied. It is found that the Arbuzov rearrangement of these compounds was accompanied by the phosphorus-carbon bond cleavage with unique retention of the three-coordinate phosphorus.

Reactions of Electron-Rich Heterocycles with Orthocarboxylic Acid Derivatives, 10. - Formylation and Alkylation of Carbazoles with Ambident Dialkoxycarbenium Tetrafluoroborates

Carbazole and some derivatives were formylated regioselectively with diethoxycarbenium tetrafluoroborate.The thermodynamically more stable diethoxymethylcarbenium and trimethoxycarbenium ions exhibit ambident electrophilic reactivity as predominant alkylation reagent.

Benzoisobenzofuran. Formation and Reactions of the Parent and Alkoxy-Substituted Derivatives

Benzoisobenzofuran (1) is formed by base-induced 1,4-elimination of either acetal 9 or 11 and may be isolated in high yield as a cristalline solid.Cycloaddition reactions of preformed 1 have been carried out with various dienophiles.These reactions may also be accomplished by heating the acetals in the presence of dienophiles and acid catalyst, where 1 is generated as an intermediate.The cycloaddition reaction of 1 and maleic anhydride is found to be reversible at higher temperature (slow at 60 deg C).Unsymmetrical dienophiles react with 1 to give equal amounts of regioisomers, and evidence points to lack of regioselectivity under both kinetically controlled and equilibrating conditions.The acetals 9 and 11 are shown to interconvert with acid catalyst at 140 deg C, where 1 is an intermediate of greater stability than the acetals; the equilibrium K for 9 -> ( - ) 11 is approximately unity.Various acid-catalyzed cycloaddition reactions of ortho esters 8 and 10, yielding polysubstituted phenanthrene derivatives, are described.
