The invention is a genus of compounds of the formula ##STR1## wherein X is --OH, --OM, --OR or --NH.sub.2 ; Y is H, M or R'C0--; R is a primary or secondary C.sub.1 --C.sub.12 alkyl group, a C.sub.5 --C.sub.7 cycloalkyl group, phenyl or a C.sub.7 --C.sub.12 phenalkyl or alylphenyl group; R' is a C.sub.1 --C.sub.11 alkyl or alkenyl group, a C.sub.5 --C.sub.7 cycloalkyl or cycloalkenyl group, phenyl or a C.sub.7 --C.sub.12 phenyl alkyl, phenylalkenyl, alkylphenyl or alkenylphenyl group and M, independently, is a metal or ammonium cation. The compounds in which X is --NH.sub.2 are uniquely selective post-emergent herbicides for control of both broadleaf weeds and wild oats in grains such as wheat and barley. The compounds in which X is not NH.sub.2 have utility as intermediates and some of them are biologically active.
该发明涉及一类化合物,其化学式为##STR1## 其中X为--OH、--OM、--OR或--NH.sub.2;Y为H、M或R'C0-;R为一级或二级C.sub.1-C.sub.12烷基、C.sub.5-C.sub.7环烷基、苯基或C.sub.7-C.sub.12苯基烷基或烯基苯基基团;R'为C.sub.1-C.sub.11烷基或烯基基团、C.sub.5-C.sub.7环烷基或环烯基基团、苯基或C.sub.7-C.sub.12苯基烷基、苯基烯基、烷基苯基或烯基苯基基团,而M独立地为金属或铵阳离子。其中X为--NH.sub.2的化合物是独特的选择性后出芽除草剂,用于控制小麦和大麦等谷类作物中的阔叶杂草和野燕麦。而X不为NH.sub.2的化合物具有中间体的用途,其中一些具有生物活性。
