A new model for the coenzyme B12catalysed methylmalonyl–succinly rearrangement incorporating peripheral A–T base pairing
摘要:
A novel B-12 derivative 4 containing a peripheral thymine group is alkylated under reductive conditions with 2-bromo- methyl-2-methylmonothiomalonate 8 bearing the complementary adenine; photolysis in chloroform-acetonitrile gives the rearranged succinate 12 and dimethylmalonate 13 (2:1), whereas in MeOH-H2O only the dimethylmalonate 13 is formed.

The rearrangement of 2-bromomethyl-2-methylmonothiomalonates to succinyl derivatives was found to take place in quantitative yields in the presence of one molar equivalent of Co(I) generated by the reduction of heptamethyl Co(II)yrinate perchlorate with NaBH4 or electrochemically. The chiral thiomalonate gave racemic succinate.
