New four-component condensations leading to 2,4,5-trisubstituted oxazoles
摘要:
A one-pot reaction leading to the title compounds has been developed based on the in situ acylation and hydroxyarylation of 5-aminooxazoles at the 4-position of the heterocycle. (C) 2003 Elsevier Ltd. All rights reserved.
A general synthesis of 2-substituted-5-aminooxazoles: building blocks for multifunctional heterocycles
摘要:
Condensation of unsubstituted isocyanoacetamides with aldehydes and ketones, or their derived iminium ions, leads to 2-substituted-5-aminooxazoles, which are useful compounds for drug discovery programs. (C) 2003 Elsevier Ltd. All rights reserved.
