The synthesis of a series of novel 4,5-dihydro-4-oxo-2-(substituted amino)-3-furancarboxylic acids, salts, esters, and amides is described. The title compounds when tested in the mediator-induced dermal vascular permeability and active anaphylaxis assays in rats demonstrated moderate to potent antiallergic activity. The [2-trans-(4-methylphenyl)cyclopropyl]amino analogue 53 emerged as the most active

2-phenyliminothiazolines of the following formula I, their salts, their preparation method and their use for treating rice blast. The phenyliminothiazolines and their salts of the present invention have low toxicity to environment or living organisms, and exert high activity at low concentration for treating rice blast through a new controlling mechanism, that is by inhibiting pentaketide synthesis and cyclization of the melanin sythesis process in formula I.
