✦ Synopsis

Recently we reported on the reactions of cyclic g-diketones and carbethoxycycloalkanones with compound I under basic catalysis.

2 In monoglyme, the products obtained were, invariably a mixture of tautomers arising from protonation of an initially formed 1,6-adduct. In DMSO the products were derivable from the sequence (i) 1,6-addition; (ii) proton transfer; (iii) intra-
