Synthesis of programmable tetra-ortho-substituted biaryl compounds using Diels-Alder cycloadditions/cycloreversions of disubstituted alkynyl stannanes

Orthogonally functionalized, programmable biaryl templates have been synthesized utilizing aryl acetylenic stannanes and oxygenated dienes in a cycloaddition/cycloreversion strategy. Sequential functionalization of each of the four ortho positions has bee

Reactions of Trialkylsilyl Trifluoromethanesulfonates, III. - Synthesis of 1,3-Bis(trimethylsiloxy)-1,3-dienes and 3-Trimethylsiloxy-2-butenoates Silylated in Position 4

Bis(trimethylsiloxy)-1,3-dienes 5a - n are obtained by reaction of 1,3-dicarbonyl compounds 1 with trimethylsilyl trifluoromethanesulfonate (2) in the presence of triethylamine (3).The silyl enol ether 8 is silylated by 2/3 to yield 1,3-bis(trimethylsiloxy)-1,3-butadiene (5o).Depending on the conditions, alkyl 3-oxobutanoates 12 react with 2/3 to give the γ-silylated alkyl 3-trimethylsiloxy-2-butenoates 15 or 16.

A Convenient Synthesis of Hydroxyphthalides

The Diels-Alder reaction of in situ generated cyclohexa-1,3-dienes with methyl 4,4-diethoxybut-2-ynoate (1) followed by reverse Diels-Alder and hydrolysis affords substituted hydroxyphthalides in good yield.
