Synthesis of oxathiane and morpholine from acyclic precursors: A modified Mitsunobu reaction

Synthesis of a set of isomeric 2,4,6-triarylmorpholines and 2,6-diaryloxathianes from the corresponding 1,5-diols has been described. The method provides an efficient route to six-membered heterocycles from acyclic diols and is found to be better than Mitsunobu procedure in yield and waste management. In a related study, the ring contraction of pyranone to two isomeric cyclopentenone derivatives through Nazarov reaction has been noticed.

Study on photochromism of diarylethenes with a 2,5-dihydropyrrole bridging unit: A convenient preparation of 3,4-diarylpyrroles from 3,4-diaryl-2,5- dihydropyrroles

Symmetric and nonsymmetric diarylethenes with a 2,5-dihydropyrrole bridging unit have been prepared, and the photochromic properties are investigated. Both symmetric and nonsymmetric diarylethenes with 2,5-dihydropyrrole bridging units undergo reversible ring-opening and ring-closing photoisomerization reactions in nonpolar solvents with UV/vis light, and some of them exhibit good fatigue resistance and no marked degradation detected after 10 cycles via an on/off switch. In polar solvents, however, photochromic diarylethenes with 2,5-dihydropyrrole bridging units produce 3,4-diarylpyrrole derivatives instead of the ring-closing isomer of diarylethenes with UV light irradiation. A class of N-substituted 3,4-diphenylethenes with 2,5-dihydropyrrole bridging units were prepared and used as templates to investigate the conversion reactions. The mechanism of photoconversion of 3,4-diaryl-2,5-dihydropyrroles to 3,4-diarylpyrroles was explored as well.
