JACOBS, Ph.D. Food, Drug and Insecticide Admin. U. S. Dept. of Agr. 1927 Chemist Department of Health, City of New York, 1928. Formerly, Lt. U. S.

A. by WAVERLY PRESS, BALTIMORE, MD. PREFACE Relatively little has been written in the United States of America on the subject of passive defense, or as we would put it, civilian defense against poison gas. One of the very first steps in defense of this nature is a system for the detection, the sampling and the identification of the chemical war- fare agents, and the decontamination of areas and materials polluted by them. It is the aim of this book to present these subjects so that the informa- tion given will be useful to the gas identification officer, the war gas chemist, the decontamination officer, and the health officer. While this book was written primarily for the aforementioned officers, Chapters I, II, III, part of IV and VII should prove of value to the air raid warden and, in general, to all persons dealing with the above mentioned phases of gas defense. It is written so that it can be used for the training of gas identifi- cation officers, as a manual by chemists and decontamination officers, and as a source of information on the analytical chemistry of the war gases.

The total synthesis of these products is very desirable since total synthesis of a compound affords a method by which final, con- clusive proof of its structure may be obtained. In addition, the total synthesis might prove economically feasible. For these reasons many workers have attempted to totally synthesize various natural products and their analogs. One of the outstanding examples of the synthesis of a rel- atively complex natural product was that of the female sex hor- mone, equilinln (II), by Bachmann, Cole, and Wilds (1) in 1959- 1940. The last portion of this synthesis utilized the cyclic ketone, 7-methoxy-l-keto-l ,2,5,4 tetrahydro phenanthrene (I) as a key Intermediate.

The earliest chemical attack occurred on the Western Front in October 1914 in Neuve Chapelle, but its effects were so minimal that the Allies learned about it only after the war from German documents. The attack in the Bolimow area, carried out by the Germans against the Russian army with artillery shells containing gas T (xylyl and benzyl bromides), was therefore the first attack on a massive scale recorded on the victim side. The attack, which occurred after it, made it possible to obtain some tactical success, but without a strategic breakthrough. Some of the later German attacks on the Eastern Front where chlorine was used proved to be more effective, but despite many victims there was not any major strategic success achieved. The Russians did not take attempts to use chemical weapons in the World War I.

Received: 30 August 2020; Accepted: 2 October 2020; Published: 3 October 2020 Abstract: Owing to their abundance in biomass and availability at a low cost, carbohydrates are very useful precursors for products of interest in a broad range of scientific applications. For example, they can be either converted into basic chemicals or used as chiral precursors for the synthesis of potentially bioactive molecules, even including nonsaccharide targets; in addition, there is also a broad interest toward the potential of synthetic sugar-containing structures in the field of functional materials. Synthetic elaboration of carbohydrates, in both the selective modification of functional groups and the assembly of oligomeric structures, is not trivial and often entails experimentally demanding approaches practiced by specialized groups. Over the last years, a large number of solvent-free synthetic methods have appeared in the literature, often being endowed with several advantages such as greenness, experimental simplicity, and a larger scope than analogous reactions in solution. Most of these methods are catalytically promoted, and the catalyst often plays a key role in the selectivity associated with the process. This review aims to describe the significant recent contributions in the solvent-free synthetic chemistry of carbohydrates, devoting a special critical focus on both the mechanistic role of the catalysts employed and the differences evidenced so far with corresponding methods in solution.
