BASIC MEDIA BEHAVIOR OF N- ETHYL CARBAMATES (Y=SMe, SOMe, SO2Me, H, Br, CN)
From the results obtained in the hydrolysis reaction of the carbamate group of some thioderivatives compounds whose common structure is (2-EtOOCNH-C6H4)-CHOH-CH2Y a mechanism is suggested to explain the products, as well as the relationship between the relative configuration of diastereoisomeric sulfoxides (Y=SOMe) with the reaction rate and with the stereochemical outcome.Other interesting and unexpected products are yielded when the hydrolysis reaction of other carbamates (Y=H, Br, CN) is carried out.In the present cases, the carbamate function seems to behave as a very versatile group capable of readily undergoing conversions to several kinds of heterocycles.

The present invention relates to novel sulfonamide derivatives, to processes and intermediates for preparing them, to plant growth regulator compositions comprising them and to methods of using them for controlling the growth of plants, improving plant tolerance to abiotic stress (including environmental and chemical stresses), inhibiting seed germination and/or safening a plant against phytotoxic effects of chemicals.
