摘要

The readily prepared 3, 4, 7, 8-tetramethylglycoluril 1 acts as a template to promote efficient intramolecular Claisen-like condensations between two acyl groups which are attached to the-1 and-6 positions. Thus, two sequential acylations of 1 give symmetric or unsymmetric diacylglycolurils 9–18 in good yield. Treat
