Mohaddeseh Safarpoor Nikoo Langroodi was born in Langrood, Guilan, I.R. Iran. She received B.S. in chemistry from Shahid Beheshti University (2006) and his M.S. in organic chemistry from University of Guilan (2010) under the direction of Professor Farhad Shirini. After two years, she began her Ph.D. studies at University of Guilan under supervision of Professor Farhad Shirini. Her current resea...
Discoveries in organic chemistry have had profound impacts in many disciplines of science through the past century. Within the field of organic chemistry, research in total synthesis of natural products has provided a means of developing and advancing the study of different types of chemistry. The discovery of novel chemical transformations, use of total synthesis products in biochemical assay ...
Organic chemistry has mainly developed with the use of second-row elements such as carbon, oxygen, and nitrogen, while the synthesis and isolation of the heavier congeners of typical organic molecules as stable compounds has been a dream for organic chemists. Our main research interest is the elucidation of the similarities and differences in structures and reactivities between organic compound...
Even if water is the natural environment for bioorganic reactions, its use in organic chemistry is often severely limited by the high insolubility of the organic derivatives. In this review, we introduce some examples of the use of water to perform organoselenium chemistry. We mainly discuss the advantages of this medium when the recyclability is demonstrated and when the water can control the ...
Approaches to research in organic chemistry are as numerous as the reactions they describe. In this account, we describe our reactivity-based approach. Using our work in the area of gold-catalysis as a background, we discuss how a focus on reaction mechanism and reactivity paradigms can lead to the rapid discovery of new synthetic tools.
What do we mean by a “supramolecular control” of a photochemical reaction? To answer this question, we will integrate the fundamental and familiar paradigm of molecular organic photochemistry (e.g., the R + hν → ∗R → I → P sequence) with the paradigm of supramolecular organic chemistry (guest@host chemistry). It will be convenient to consider supramolecular control of unimolecular and bimolecul...
A general mathematical description, mostly in terms of graph theory, is given for reactions of organic chemistry. The corresponding computer program generates all products that can result from a given set of starting materials interacting according to a given set of reaction schemes. Example reactions from combinatorial chemistry, synthetic organic chemistry, and mass spectroscopic structure el...

This perspective delineates the history of the National Organic Chemistry Symposium (NOS) and, in doing so, traces the development of organic chemistry over the past 88 years. The NOS is the premier event sponsored by the ACS Division of Organic Chemistry (ORGN) and has been held in odd-numbered years since 1925, with the exceptions of 1943 and 1945. During the 42 symposia, 332 chemists have gi...
