A concise synthesis of the fredericamycin A DEF ring system: [4 + 2] cycloaddition reactions of 1-aza-1,3-butadienes
摘要:
A concise four-step synthesis of the fredericamycin A DEF ring system is detailed based on the LUMO(diene)-controlled Diels-Alder reaction of N-sulfonyl-1-azadiene 3 for introduction of the pyridone F ring.
