The intramolecular Diels-Alder reactions involving boryl-3-propenoic acid derivatives has been addressed to. So, heating the trienylamide (7) at 80°C in toluene for 15 hours led to a 1/3 mixture of the cycloadducts (8) and (8 ) isolated in 72 % yield (figure 6) l7. The trienylamide (9) could not be isolated since the IMDA occured at the temperature of the coupling step, i,e below 0°C in ether for 30 minutes. This very fast cyclisation led to a 85/15 mixture of cycloadducts (10) and (10 ) having respectively a cis and trans junction in the bicyclic structure. The cis bicyclic structure (10) results from an endo approach of the diene and the dienophile. This is in agreement with literature data l8. [Pg.467]

The addition of a-(acylamino) esters to 3-aryl-2-propenoates, with sodium ethoxide in ethanol or sodium hydride in benzene as base, is a frequently ultilized procedure9-" A The initial Michael adducts cyclize to 3-aryl-5-oxo-2-pyrrolidinecarboxylic acids with modest to high trans diastereoselectivities 10°.

An excellent method for the diastereoselective synthesis of substituted amino acids is based on optically active bislactim ethers of cyclodipeptides as Michael donors (Schollkopf method, see Section 1.5.2.4.2.2.4.). Thus, the lithium enolates of bislactim ethers, from amino acids add in a 1,4-fashion to various a,/i-unsaturated esters with high diastereofacial selectivity (syn/anti ratios > 99.3 0.7-99.5 0.5). For example, the enolate of the lactim ether derivative 6, prepared from (S)-valine and glycine, adds in a highly stereoselective manner to methyl ( )-3-phenyl-propenoate a cis/trans ratio of 99.6 0.4 and a syn/anti ratio of 91 9, with respect to the two new stereogenic centers, in the product 7 are found105, los.
