A simple synthesis of functionalized (1H)-quinol-2-ones and quinolines from the Baylis-Hillman adducts, i.e. alkyl 3-hydroxy-2-methylene-3-arylpropanoates and β-hydroxy-α-methylene-β-arylalkanones, respectively, has been described.

An efficient Lewis acid-catalyzed C(sp3)–C(sp3) bond forming annulation reaction has been developed. This strategy serves as a new method for the facile synthesis of tetrahydro-5H-isoquinolino[2,1-g][1,6]naphthyridine derivatives. A wide range of 2-methylquinoline-3-carbaldehydes and 1,2,3,4-tetrahydroisoquinolines can be applied for this process to afford structurally diverse tetrahydroprotoberberine derivatives in excellent yields.

, p. 6474 - 6477 (2017/08/16)
A catalytic asymmetric method for the synthesis of chiral isoquinolinonaphthyridines has been developed. A chiral disulfonimide catalyzes a redox cyclization reaction between 2-methyl-3-aldehydeazaarenes and 1,2,3,4-tetrahydroisoquinolines to deliver a range of isoquinolinonaphthyridines with good to high yields (up to 91%) and up to 92:8 er.

Amines such as 1,2,3,4-tetrahydroisoquinoline undergo redox-neutral annulations with 2-alkylquinoline-3-carbaldehydes as well as the corresponding 4-alkyl isomers and pyridine analogues. These processes involve dual C-H bond functionalization. Acetic acid
Palladium(II)-Catalyzed ortho-Arylation of Aromatic Alcohols with a Readily Attachable and Cleavable Molecular Scaffold
Li, Qiankun,Knight, Brian J.,Ferreira, Eric M.
supporting information, p. 13054 - 13058 (2016/09/09)
A palladium(II)-catalyzed C?H arylation process of alcohols has been developed. The strategy utilizes a novel quinoline-based hemiacetal scaffold that can direct the selective C?H bond functionalization. This reaction provides a useful method to construct biaryl compounds of benzyl alcohols in good to excellent yields. The new molecular scaffold can be readily attached, removed, and recovered.
Synthesis of an analogue of lavendamycin and of conformationally restricted derivatives by cyclization via a hemiaminal intermediate
Nourry, Arnaud,Legoupy, Stéphanie,Huet, Fran?ois
, p. 6014 - 6018 (2008/02/10)
Quinoline 12 was obtained by a Friedl?nder reaction from 2-aminobenzaldehyde and methyl acetoacetate. Reduction, silylation then oxidation provided compound 8a. A Pictet-Spengler reaction between the latter and tryptophan methyl ester yielded compound 14,
