Pd(OAc) 2 was found to be an efficient catalyst for the macrocyclization of 1,2-diazonaphthoquinones and cyclic ethers. This transformation serves as an efficient method for the synthesis of protected 1,2-naphthalenediols.
Ethers. -The reaction of (Ic) with (II) does not yield the corresponding cyclization product, but a dimer via linkage of the two diazo groups. -(KITAMURA*, M.; KISANUKI, M.; KANEMURA, K.; OKAUCHI, T.; Org.
