## Abstract The structures of the previously reported arylβperhydroβ1,3βdiazepineβ2,4βdiones are shown to be pyrroβlidinone carboxamide derivatives by nmr spectroscopy.
Furan-2-acetic esters are obtained in good yields by direct oxidative cyclization-alkox~.'carbonylation of (Z)-2-en-4-yn-l-ols. bearing both an alkyl or an aD'l substituent a to the hydrox3' group, in the presence of catalytic amounts of palladium iodide in conjunction with potassium iodide at 50-70
