Synthesis of (E)-4-ethoxyphenyliminomethylaryls and their hydrochlorides
摘要:
Condensation of p-phenetidine with the substituted aromatic benzaldehydes in methanol results in (E)-4-methylethoxyphenyliminoaryl derivatives. The latter react with gaseous hydrogen chloride in diethyl ether to form 4-ethoxymethylphenyliminoaryl hydrochlorides.

Synthesis of Heterocycles with MF/Al 2 O 3 Base-Systems: 2-Arylbenzofuranes and 2,3-Diarylisoquinolin-1(2H)-ones2-Benzyloxybenzaldehydes, -acetophenones and -benzophenones substituted in the benzyl part with electron-withdrawing groups, cyclize easily to 2-arylbenzofuranes by using a standardized KF- or CsF-Al2O3 base system. An efficient one-pot synthesis for 2,3-diarylisoquinolin-1(2H)-ones is possible by reacting a variety of arene carbaldehyde anils with phthalides under the same reaction conditions.

A mild, efficient, and general method for the synthesis of substitutedquinolines via a molecular iodine-catalyzed one-pot domino reaction of imines with enolizable aldehydes has been described.
Reactions of 4-pyridinecarbomitrile with sodium and aromatic imines provide a convenient and useful method for synthesising a new kind of substituted 4-pyridinemethanamines in good yields.
