The acetone-initiated photochemical alkylation of protected glycylglycine, glycylalanine, and glycyl-leucine dipeptide methyl esters with isobutene, but-1-ene, and toluene is described. The reactions lead to the preferential conversion of the glycine residue to leucine, norleucine, or phenylalanine, respectively, in yields of up to 60%. A free-radical chain mechanism is proposed for these reactions
描述了用异丁烯,丁-1-烯和甲苯进行的丙酮引发的被保护的甘氨酰甘氨酸,甘氨酰丙氨酸和甘氨酰亮氨酸二肽甲酯的光化学烷基化。反应导致甘氨酸残基分别优先地转化为亮氨酸,正亮氨酸或苯丙氨酸,产率最高为60%。提出了针对这些反应的自由基链机制。
