Embodiments of this disclosure, among others, encompass methods for generating alkenes under mild thermolytic conditions that can provide almost total conversion of a precursor compound to an alkene without isomerization or the need to chromatographically purify the final product By selectively blocking the amino and carboxy groups of the deπvatized amino acid, the methods of the disclosure provide for the synthesis of a peptide having the vinylglycine moiety at either the carboxy or the amino terminus of the peptide The mild conditions for the thermolytic removal of an o-NO
2
-phenyl substituted aryl group ensure that there is minimal if any damage to thermally sensitive conjugates such as a peptide bearing the vinylglycine The methods of the present disclosure have practical applications for the preparation of unsaturated compounds under mild, thermolytic conditions.
The present invention provides an intermediate compound for easily producing a compound having an azaperylene skeleton. Another object of the present invention is to provide a method for easily producing a compound having an azaperylene skeleton.
The compound of the present invention is a compound represented by Formula (I), or a compound represented by Formula (II).

The present invention discloses dye-sulfenate derivatives and their bioconjugates for dual phototherapy of tumors and other lesions. The compounds of the present invention may contain either a mixture of type 1 and type 2 agents or a single entity that integrates both units in the same molecules. The compounds are designed to produce both type 1 and type 2 phototherapeutic effect at once using dual wavelength light source that will produce singlet oxygen and free radicals at the lesion of interest.
