Methional derivatives and compositions with a growth-regulating effect upon plants

摘要

Plant growth-regulating compounds of the formula <IMAGE> wherein X and Y are separately oxygen, sulfur, N-B where B is hydrogen, lower alkyl, or acyl; R and R' are separately lower alkyl, acyl, amido, or form a cycle with <IMAGE> corresponding to the formula <IMAGE> in which R1, R2, R3, and R4 are separately hydrogen, lower alkyl, halogen-substituted lower alkyl, NO2, hydroxy or lower alkoxy, and A is a single bond or an alkylene chain of 1-4 carbons, or an alkylene chain of 1-4 carbons interrupted by oxygen or N-B' where B' is hydrogen, lower alkyl, lower halogen-aided alkyl, lower hydroxylated alkyl, lower acyl, or a cycle having in common with the preceding cycle 1 or 2 carbon atoms and containing from 3 to 6 carbons, up to 2 oxygens and/or a group N-B, or a cycle corresponding to the formula <IMAGE>
