2-chloro-2-cyclopropylidenacetates

Methyl 2-chloro-2-cyclopropylidenacetate (4) cleanly and quantitatively dimerizes at 120 °C to afford a 1 1 mixture of cis and trans dispirooctane 46 diastereoisomers (Scheme 65, X = Cl) [7,20]. [Pg.75]

Methyl 2-chloro-2-cyclopropylidenacetate Acetic acid, chlorocyclopropylidene methyl ester (11) (82979-45-1)... [Pg.153]

CHLORO-2-CYCLOPROPYLIDENACETIC ACID, METHYL ESTER ACETIC ACID,... [Pg.271]

A domino Michael addition/Sj sequence has been elaborated by the group of de Meijere [155]. In this example, basic treatment of 2-chloro-2-cyclopropylidenacetates 306 with carboxamides 307 forms 4-spirocyclopropane annulated oxazoUne-5-carboxylates 310 (Scheme 7.74). As intermediates, the carbanion 308 and anion 309 have been proposed. [Pg.262]
