Reaction of hemicyclone (10) with (E)-1,4-dibromobut-2-ene (9) under forcing conditions yielded a 1:1 adduct (11) which served as the precursor for the 5,6-bismethylenenorborn-2-en-7-one (12) through fluoride-promoted dehydrobromination. The conjugat

N-Methylmaleimide-fused cyclobutadiene (15) and its 1,2-dimethyl derivative (41) have been generated by zinc/titanium tetrachloride treatment of the vicinal dibromide (39) and (24) respectively. Prior epoxidations of (24) and (39) produce mixtures of

Irradiation of isobenzofuran (1) in acetone solution yields a symmetrical [π8s+π8s] dimer (24) involving bonding at the peri -position of the furan moiety in each molecule. The anti-stereochemistry of this dimer was established by a novel applicati

Isoindene (1), generated by ultraviolet irradiation ( Vycor filter, acetone solution) of 1,4- dihydro-1,4-methanonaphthalene-2,3-dione (14), is shown to undergo homodimerization at -60°. This cycloaddition involves the intermolecular transfer of a h

cis-3,4-Dichlorocyclobutene (19) reacts with isobenzofuran (4) to produce three of four possible [ π;45+π 28] cycloaddition products. The isomer (27) is the dominant cycloadduct , which indicates that significant stabilization by the chlorine atoms

A new protocol for a general synthesis of cyclic polyenes is presented; in this protocol two new concepts are introduced. The first, acetylene stacking, is the generic term covering both the synthesis of a target molecule and the specific retrosynthe
