2-Acetyl-6-[(benzyloxy)methyl]-9-methoxy-8-methyl-11,11adihydro-2H-pyrazino[1,2-b]isoquinoline-1,4,7,10(3H,6H)-tetraone (11a) was prepared as the CDE ring model of renieramycins, and its novel photo-induced transformation was demonstrated to construct a 1,3-dioxol ring.
Approaches to the fully functionalized DEF ring system of ristocetin A via highly selective ruthenium-promoted SNAr reaction

Ruthenium-promoted intramolecular SNAr reaction has allowed the construction of the fully functionalized 16-membered DEF macrocycle 4 of ristocetin A that incorporates the required arylglycine and arylserine residues as the F and E ring, respectively.
