CONTRIBUTIONS BY PROFESSOR V. D. ORLOV TO THE CHEMISTRY OF NITROGEN HETEROCYCLES

Abstract
This article provides a general overview and detailed discussion on the research by Professor V. D. Orlov (at the Chair of Organic Chemistry, Kharkiv V. N. Karazin National University) regarding the synthesis, structure, and reactivity of three-, five-, six-, and seven-membered azaheterocycles, covering the time period starting in the middle of 1970's.
