Coates and Shaw found that vinylogous amide 11.1 reacts with trans-3-penten-2-one to provide a 91 9 (trans/cis) mixture of diastereomers (Scheme 11) (24). Choice of solvent is critical in formamide, a 50 50 mixture of diastereomers is produced. [Pg.98]

You should convince yourself that cis-3-pentene is identical to cts-2-pentene and trans-3-pentene is identical to trans-2-pentene. However, cis-2-pentene and trans-2-pentene are the correct names because they have smaller numbered prefixes.)... [Pg.1053]

Predict the preferred conformation of the isomeric (cis- and trans ) 3-penten-2-ones, A, R=CH3. How would you expect the conformational picture to change as R becomes progressively larger ... [Pg.177]

Solvents can influence the stereochemical outcome of the Robinson annulation. An interesting example is the one-step annulation using the sodium enolate of 49 to give the octalone 54 and 55. The reaction of the sodium enolate of the 2-methyl-cyclohexanone with trans-3-penten-2-one (53) in the presence of dioxane at room temperature for 100 h gives the cis-4,10-dimethyl-A octal-2-one (54) in 65% yield, while the reaction gives the /ra -isomer 55 in 72% yield in 3 h under same conditions. ... [Pg.397]
