Ec 400

The ¹H, ¹³C NMR spectra were recorded on JEOL EC-400, EC-500, and EC-600 spectrometers using a residual solvent peak as a reference. Compounds for HRMS were analyzed by positive mode electrospray ionization (CI or ESI) using an Agilent QTOF mass spectrometer in the Mass Spectrometry Facility (MSF) of the Department of Chemistry and Biochemistry of University of Texas–Austin. Column chromatography was performed using 60 A silica gel. Reagents and starting materials were purchased from commercial vendors and used without further purification unless noted otherwise.

Compounds for HRMS were analyzed by positive-mode electrospray ionization (CI or ESI) using Agilent QTOF mass spectrometer in the Mass Spectrometry Facility (MSF) of the Department of Chemistry and Biochemistry of the University of Texas, Austin. IR spectra were obtained using a ThermoScientific Nicolet iS10 FT-IR spectrometer. Column chromatography was performed using 60 Å silica gel. Reagents and starting materials were purchased from commercial vendors and used without further purification. Ozonolysis was conducted using Ozone Solution OZV-8 ozone generator and oxygen (oxygen, Matheson, 99.98%). The amount of ozone was regulated by flow rate and the 10-position switch integrated into the device (intensity 1–10).
