The fused tetrahydropyran-2-one (566) is obtained from 2-methylcyclohexanone by Michael addition to methyl prop-2-enoate and reduction of the resulting keto ester (565 Scheme 216) (63JOC34). When the enamine derived from the cyclohexanone reacts with the unsaturated ester, a mixture of keto esters (565) and (567) is formed. The pyranone (568) is formed by reduction of the latter.

A two-phase mixture of methyl propiolate (5.0 g, 59.5 mmol), boric acid (5.5 g, 89 mmol), sodium benzenesulfinate (9.75 g, 59.5 mmol), and tetra-n-butylammonium hydrogen sulfate (3.0 g, 8.75 mmol) (Note 1) in tetrahydrofuran water (200 mL, 1 1) is stirred vigorously at room temperature for 48 hr (Note 2). The solution is acidified to pH 4 (2 N hydrochloric acid) and extracted into diethyl ether (4 x 50 mL) (Note 3). The organic layer is dried (MgSCU) and concentrated under reduced pressure to afford 13.75 g of yellow oil (Note 4) which is subjected to flash column chromatography (1.5 1 hexanes-diethyl ether) to afford initially methyl (E)-3-(benzenesulfonyl)prop-2-enoate (400 mg, 2.9%) and then the desired Z-isomer (10.89 g, 81%) as a pale yellow solid, pure by spectral study (Note 5). 

This procedure describes the short, one-pot, high-yield preparation of methyl (Z)-3-(benzenesulfonyl)prop-2-enoate. This route is shorter than a previously reported preparation.2 We have been able to apply this technique to the preparation of a highly functionalized suifonyi acrylate, although the generality of this reaction has not been studied (eq. 1 ).3...

Trifluoroethyl 2-(trifluoromethyI)prop-2-enoate reacts with various dienes to provide cycloadducts in high yields. A typical example is the reaction with ( )-l-methoxy-2-methyl-3-(trimethylsiloxy)buta-l,3-diene leading to the trifluoromethyl-substituted cyclohexenone 13 which was used as a precursor of 16,16,16-trifluororetinal." The reaction has also been performed with a chiral dienophile."...

With palladium catalysts, such as bis(dibenzylideneacetone)palladium/triisopropylphosphane (1 1) or tris(acetylacetonato)palladium/triisopropylphosphane/ethoxydiethylaluminum (1 1 2), 3,3-dimethylcyclopropene can be reacted in methyl acrylate as solvent to yield small amounts (about 10%) of cotrimers constisting of two molecules of the cyclopropene and one molecule of methyl acrylate, namely, a 1 1 mixture of methyl 3-[2,2-dimethyl-3-(2,2-dimethyl-cyclopropyl)cyclopropyl]prop-2-enoate isomers 40 and methyl 3,3,8,8-tetramethyltri-cyclo[5.1.0.0 ]octane-5-carboxylate (41). These compounds can be obtained in far better yield using trialkylphosphane-modified nickel(O) catalysts (see above). Major products of the palladium-catalyzed reaction are the homo-cyclodimer, 3,3,6,6-tetramethyl-exo-tricy-clo[3.1.0.0 ]hexane (55%), and the homo-cyclotrimer, 3,3,6,6,9,9-hexamethyl-crtt/o,e.TO-tetra-cyclo[6.1.0.0 - .0 ]nonane (33.5%).
