3. Unhindered secondary amines (piperidine, pyrrolidine) led exclusively to the unsaturated esters 6a of E configuration. Pyridine did not catalyze the reaction even in a prolonged reaction time. The less nucleophilic secondary amines (diisopropylamine and 2,2,6,6-tetramethylpiperidine) gave a mixture of adduct 4a and ester 6a (E) (ratio 86/14 and 74/16 respectively)
