Abstract
The following novel oligopeptide compounds which possess phytotoxic and plant growth regulating properties and methods for their use are disclosed: R.sub.1 -N(R.sub.2)-D,L-Ala-D,L-Leu-N(R.sub.2).DELTA.Phe-Gly-OR.sub.3 ; in which R.sub.1 is H or a protecting group at the amino terminus of the type 9-fluorenylmethoxycarbonyl, or benzyloxycarbonyl, R.sub.2 is an alkyl of 2 to 3 carbon atoms, R.sub.3 is hydrogen or an alkyl of 2 to 3 carbon atoms, and .DELTA.Phe is dehydrophenylalanine. R.sub.1 -D,L-Leu-N(R.sub.4)-.DELTA.Phe-Gly-OR.sub.3 ; R.sub.1 Aib-N(R.sub.2)-.DELTA.Phe-Gly-OR.sub.3 ; R.sub.1 -Ala-N(R.sub.5)-.DELTA.Phe-Gly-OR.sub.3 ; R.sub.1 -Val-N(R.sub.2)-.DELTA.Phe-Gly-OR.sub.3 ; wherein R.sub.1 is H or a protecting group at the amino terminus of the type tert-butyloxycarbonyl-(BOC), 9-fluorenylmethyloxycarbonyl, or benzyloxycarbonyl, R.sub.2 is an alkyl of 1 to 3 carbon atoms, R.sub.3 is hydrogen or an alkyl of 1 to 3 carbon atoms, and .DELTA.Phe is dehydrophenylalanine.
