The cyclic parent (II) of the title series, and the following 1- or/and 4-substituted derivatives therefrom: 4-ethoxycarbonyl (III), 1-phenyl-4-ethoxycarbonyl (IV), and 1-phenyl (V), were prepared by conventional methods. (III) and (IV) gave each a single product on methylation with ethereal diazomethane. Structures of these products, and those of (II) - (V), are discussed on the basis of proton magnetic resonance and infrared spectra
