Autor: Yoshikazu Kubota, Lelia M. Fuentes, Albert I. Meyers
Publikováno v: Tetrahedron. 40:1361-1370
A series of chiral amino alcohols transformed into the formamidine derivative of 1, 2, 3, 4-tetrahydroisoquinolines were evaluated as chiral dipole-stabilized anions. Alkylation with alkyl halides provided the 1-alkyl-l, 2, 3, 4-tetrahydroisoquinolin
