Coumarins: Fast Synthesis by Knoevenagel Condensation under Microwave Irradiation
Bogdal, Dariusz
, p. 468 - 469 (1998)
Condensation of salicyaldehyde or its derivatives with various derivatives of ethyl acetate in the presence of piperidine leads to the synthesis of coumarins by a solvent free reaction under microwave irradiation.
A Simple Route to N(2'-Hydroxy)-arylidene-nitroanilines-Versatile Synthones for Coumarines
Czerney, P.,Hartmann, H.
, p. 21 - 28 (2007/10/02)
In a three-component reaction with ortho formic esters and nitroaniline activated phenols are easily transferred to N(2'-hydroxy)-arylidene-nitroanilines.The reaction is commonly applicable and gives the N(2'-hydroxy-4'-N,N-dialkylamino)-benzylidene-nitroanilines 10 in good yields also with the air-unstable m-N,N-dialkylaminophenols 8.The prepared 2-hydroxy-azomethines are convertable into boroncomplexes 14 and coumarine derivatives 17, respectively.
