Structure activity relationship studies of new ethylene antagonists

Abstract

Ethylene antagonists provide one of the most effective methods to reduce postharvest losses of horticulture produce. The understanding of the mode of action of 1-methylcyclopropene led to the discovery of a new class of ethylene antagonist. Cycloproparenes, benzocyclopropene and 1H-naphtho[b]cyclopropene were prepared and showed excellent inhibition of the effect of ethylene on some fruits and waxflowers.
