Bohlmann, Ferdinand published the artcileLupine alkaloids. XXVII. The effect of amino groups on the rate of solvolysis of esters, Recommanded Product: 1-Ethylpiperidin-3-ol, the publication is Chemische Berichte (1964), 97(6), 1619-24, database is CAplus.
cf. CA 61, 31542. The rates of solvolysis of a series of aminoalkyl azobenzenecarboxylates were investigated. The equatorial esters were always solvolyzed faster than the axial ones. The strong acceleration of the reaction by more remotely located amino and lactam groups is noteworthy. The rates of the solvolysis were determined for the azobenzenecarboxylates of the following alcs.
