Quinoline derivatives
R 0410
A Simple and Efficient Synthesis of New Dihydrospiro[(1H)quinoline-2,1'-cycloDerivatives via Internal Friedel—Crafts Alkene Alkylation of N-(1-Allyl32- 144 hexane]
cyclohexanyl)ethylphenylamine. — A new and practical synthesis of the title spiranes
(VII) and (VIII) via internal Friedel—Crafts alkene alkylation reactions is described.
N-Allylated spirane (VII) is transformed into 8-allylspiroquinoline (IX) via an amino-Claisen transposition and into the new unnatural lilolidine derivative (X) via a second
internal alkylation. — (KOUZNETSOV*, V. V.; DUARTE, L. D. A.; STASHENKO,
E. E.; Synth. Commun. 35 (2005) 4, 621-629; Lab. Sint. Org. Fina, Esc. Quim., Univ.
