Reaction of the n-butyl esters of alanine and leucine with both tert-butyl-1,4-benzoquinone and 1,4-naphthoquinone gave the corresponding N-substituted quinones. Substitution at both C-5 and C-6 was observed with 2-tert-butyl-1,4-benzoquinone, but C-6 substitution predominated. Reduction of the latt
