The results obtained for the asymmetric 1,4-addition of arylboionic acids to crotonates or cinnamates in the presence of a Rh(acac)(C2H4)2-(S)-binap catalyst are summarized in Table 3. The ester group (R2) significantly affects the %ee. Thus, the i-propyl, cyclohexyl, (-butyl, benzyl esters achieved a high %ee whereas the methyl and ethyl esters (entries 1-4) resulted in low asymmetric induction. The absolute configuration of benzyl 3-phenylbutanoate ([a]D -14.5 (c 1.02, CHC13) obtained from (S)-binap was established to be (R) by the specific rotation reported for (R)-3-phenylbutanoic acid ([a]D -45.8 (c 0.77, benzene).

The reaction of crotonic and cinnamic acid derivatives with 296 was very dependent upon the nature of the carboxylate derivative used in the aza-annulation and the conditions of the reaction (eq. 61). When the corresponding acid chloride was used in the presence of pyridine, only A -acylation was observed to yield 303.85 However, when 296 was deprotonated with NaH and then treated with the ethyl ester of either crotonic or cinnamic acid, aza-annulation occurred to give 302.

In this way it was possible to isolate methyl-acrylic acid by the electrolysis of ethyl-potassium dimethyl-malonate, and ethyl-crotonic acid by electrolyzing a solution of the ethyl-potassium salt of diethyl-malonic acid. On the electrolysis of sebacic acid the ethyl ester of an unsaturated acid, CHj CH(CH,),.COOH, was formed. [Pg.60]
