Easy Access to 2-Alkyl and 2-Arylthiazolines Using a Modified Heteropolyacid Catalysis: Application to the Synthesis of Bacillamide A
摘要:
A straightforward access to 2-alkyl and 2-arylthiazolines by condensation of beta-aminothiols on nitriles, catalyzed by phosphotungstic acid (2%) under microwave irradiation, is described. This method has been directly applied to a short and efficient synthesis of bacillamide A (16).
