Usage

General Description

Phenoxyformohydrazide is a chemical compound commonly used as a plant growth regulator, specifically to improve fruit set and yield in agricultural crops. It is thought to function by inhibiting the synthesis of gibberellin, a phytohormone responsible for regulating plant growth and development. Phenoxyformohydrazide is often applied to fruit trees and other perennial crops to improve flowering and fruiting, and it has also been used in the production of seedless fruit, such as grapes and tomatoes. While generally considered safe for use in agriculture, the potential impacts of phenoxyformohydrazide on human health and the environment are not well understood, and research on its effects continues.

Investigation of Masked N-Acyl-N-isocyanates: Support for Oxadiazolones as Blocked N-Isocyanate Precursors

In contrast to carbon-substituted isocyanates that are common building blocks, N-substituted isocyanates remain underdeveloped and reports on their N-acyl derivatives (i. e. amido-isocyanates) are exceedingly rare. Herein, amido-isocyanates were investiga

Intermolecular aminocarbonylation of alkenes using concerted cycloadditions of iminoisocyanates

The aminocarbonylation of alkenes is a powerful method for accessing the β-amino carbonyl motif that remains underdeveloped. Herein, the development of intermolecular aminocarbonylation reactivity of iminoisocyanates with alkenes is presented. This includes the discovery of a fluorenone-derived reagent, which was effective for many alkene classes and facilitated derivatization. Electron-rich substrates were most reactive, and this indicated that the LUMO of the iminoisocyanate is reacting with the HOMO of the alkene. Computational and experimental results support a concerted asynchronous [3 + 2] cycloaddition involving an iminoisocyanate, which was observed for the first time by FTIR under the reaction conditions. The products of this reaction are complex azomethine imines, which are precursors to valuable β-amino carbonyl compounds such as β-amino amides and esters, pyrazolones, and bicyclic pyrazolidinones. A kinetic resolution of the azomethine imines by enantioselective reduction (s = 13.43) allows access to enantioenriched products. Overall, this work provides a new tool to convert alkenes into β-amino carbonyl compounds.

Synthesis of 6-carboxylated phenanthridines by oxidative alkoxycarbonylation-cyclization of 2-isocyanobiphenyls with carbazates

An iron-catalyzed synthesis of 6-carboxylated phenanthridines starting with readily prepared isocyanides and carbazates was developed. Reactions occurred via addition of alkoxycarbonyl radicals to the isocyanide group and subsequent intramolecular cyclization.
