2-Halogeno-3-morpholinothietan 1,1-dioxides. Syntheses, configurations, and conformations
Abstract
Several cis- and trans-2-halogeno-3-morpholinothietan 1,1-dioxides have been synthesized. Their configurations and conformations have been assigned from 1H n.m.r. data, including lanthanide-induced shifts. The stereo-chemical assignments agree with predicted relative thermodynamic stabilities based upon inspection of molecular models.
