reaction formally involves an unusual type of Ene reaction between 2-methylpropenal and the allylic alkoxide anion in which stepwise or highly asynchronous hydride transfer precedes carbon carbon bond formation. Under different reactions conditions the condensation of 2-methylpropenal with the potassium alkoxide of 2-methyl-2-propen-1-ol proceeds to give the bicyclic lactone, 6-endo-hydroxy-7-exo-(2-methyl
