摘要

Summary A series of 1-nitro-1-methylethyl alkyl malonic esters has been prepared by condensing 2-chloro-2-nitropropane with the sodium salt of the appropriate monoalkyl malonic ester. Catalytic hydrogenation of a representative of the series, 1-nitro-1-methylethyl ethyl malonic ester, resulted in cleavage to ethyl malonic ester. A typical member of the series, l-nitro-lmethylethyl methyl malonic ester, has been converted to the corresponding ...
