The substituted 5,10-methylenetetrahydrofolate models 5b and 7, prepared by the addition of glutaconate ester anion to 1-acetyl-3,4,4-tri-methyl-2-imidazolinium iodide (2b) and 1-acetyl-3-aethyl-1,4,5,6-tetrahydro-pyrimidinium iodide (3) transfer the C(2)-carbons with the attached functional groups to give an indole derivative which serves as a convenient precursor for the synthesis of nor-deplancheine
