摘要

The furylureas are of formula (I): where R1, R2 and R3 are 1-4 C alkyl, 2-4C alkenyl or 2-4C alkynyl, provided that the total no. of C-atoms in R1 + R2 + R3 is not 6, and that 1 of R1, R2 and R3 is alkynyl, and that two of R1, R2 and R3 together with the attached C-atom may form a cycloalkyl or cycloalkenyl group; X is CH2 opt. substd. by Me, Et, PR or Bu; R4 is H or Me, provided that when R4 is Me, X is -CH2-. Also claimed are the Na, K and Ca salts of (I) when X is CH2 opt. substd. by Me or Et. (I) are plant growth regulators and antihypertensive agents.
