note
-
For generality's sake the geometric isomers of compounds 2, 3 and 4 will be designed as cis or trans if the unsaturated moiety (β-positioned for 2 or δ-positioned for 3 and 4) and the carbonyl group are "cis"or "trans" with respect to the carbon-carbon double bond.

-
85030189442
-
-
note
-
The configuration of the α,β carbon-carbon double bond in compounds 2a-d was established by the chemical shift of the β-proton: 5.96-6.10 ppm for the cis isomer and 6.88-7.00 for the trans isomer (see ref. 12a). The cis configuration of compound 2e was established by the chemical shifts of its aromatic protons (7.12-7.36) which appeared similar to those of 2a-«s (7.15-7.38) and different from those of 2a-trans (7.25-7.41 and 7.69-7.77). The configuration of 2g-trans was established on the basis of the chemical shift.of its vinylic proton.

-
note
-
Pure analytical samples for NMR spectroscopy of each stereoisomer of compounds 2, 3a and 4 were obtained by column chromatography. In the case of 2e only the cis isomer was obtained. In the case of 2g the cis isomer was formed in a very small amount and was not characterized; the sequence was then conducted on 2g-trans .

The thermolysis of α-diazo-γ-methoxy-γ,δ-vinyl- β-ketophosphonates furnishes the corresponding cyclobutenones in good to moderate yields (see ref 15).
