000158138 520__ $$aA two-step sequence involving an Ugi four-component reaction and an intramol. nucleophilic arom. substitution (SNAr) has been developed for the rapid access to biaryl-ether contg. macrocycles. For example, reacting heptanal with butylamine, (3-hydroxyphenyl)acetic acid, and isonitrile I in dry toluene in the presence of NH4Cl gave dipeptide II. II was then cyclized using an intramol. SNAr sequence to give cyclic ether III as a mixt. of 4 diastereomers. In the course of this study, we documented that ammonium chloride can promote the Ugi-4CR in non-polar aprotic solvent (toluene) without the interference of an alternative Passerini reaction. Solid phase synthesis of macrocycles by this two-step sequence was also developed using polymer (Wang resin) supported alpha -(4'-fluoro-3'-nitro)phenethyl isocyanoacetate as one of the inputs.
