    • 1H NMR, was found to be less than 50% complete. When 3 was heated to 110 C for 16 h, when equilibrium had been achieved, 3 was found to exist as a 19:68:13 mixture of Z (S): E (S): E (R) isomers. In contrast, Enders found that the alkylated SAMP hydrazones of 2,2-dimethyl-1,3-dioxan-5-one undergo rapid isomerization from Z to E on heating, with isomerization being complete after 15 min at 50 C.
