The syntheses of potential α-sulfur-substituted carbanion precursors (2a-h) are reported and the results of their subsequent reactions with strong bases are presented. The relatively stable carbanions (3a-d) were made to react with a variety of α,β-unsaturated ketones and the yields of 1,4 and 1,2 addition products were determined.

The Michael Addition

Studies on the reactions of carcinogenic γ-lactones and related compounds with analogues of guanine DNA residues indicate that the lactones themselves will not effect permanent alkylation of the guanine N-7 position since the Michael addition reactions involved would be readily reversible. In contrast, the α,β-unsaturated acids resulting from hydrolysis of such lactones are effective guanine N-7 alkylating agents owing to zwitterionic stabilization of the corresponding Michael addition products.
