Danheiser benzannulation This reaction is quite complementary to the Wulff–Dötz reaction. This is a [2+1] cycloaddition of a carbene to an alkyne or alkene (more specifically in the Dӧtz reaction a carbene coordinated to a metal carbonyl group) to produce substituted aromatic phenols.
Danheiser benzannulation The synthesized alkynes are then heated in benzene or toluene in presence of excess cyclobutenone initiating the benzannulation reaction. Treatment with n-BuNF in tetrahydrofuran removes the siloxy groups to form the desired diols.
Danheiser benzannulation Rick Danheiser received his B.A. in 1972 from Columbia University then his Ph.D. in 1978 from Harvard University. There he studied under E. J. Corey and completed his thesis on the total synthesis of gibberellic acid. Rick currently teaches chemistry at MIT and his research group works on total synthesis of biologically active compounds and also works on annulation strategies.
Danheiser benzannulation Activated alkyoxyacetylenes can be synthesized in a single-pot preparation of triisopropylsilyloxyacetylenes from esters. The silyloxyacetylenes are useful substitutes for alkoxyacetylenes in [2 + 2] cycloaddition reactions with ketenes and vinylketenes affording cyclobutenones (Scheme 8).
Danheiser benzannulation Diazoketones can be synthesized in one-step from readily available ketones or carboxylic acid precursors by the addition of diazomethane to acyl chlorides. A diazo group transfer method can be used to produce α,β-unsaturated ketones. The traditional method of the deformylative diazo transfer approach has been improved upon by substituting the trifluoroacetylation of generated lithium enolates for the Claisen formylation step. The key step in this procedure is activation of the ketone starting material to the corresponding α-trifluoroacetyl derivative using trifluoroethyltrifluoroacetate (TFEA) (Scheme 9).
