A novel feature in phenyliodine diacetate oxidation
摘要:
Phenyliodine diacetae (PIDA) oxidation of N-benzyl-N-benzyloxy-carbonyltyrosine (4a) followed in one pot by quenching with aqueous sodium chloride or bromide solution gave the corresponding dihalodienone lactone (5a or 5b). With dihydrocinnamic acid similar feature of PIDA oxidation was obsearved. The plausible mechanism is also described.
