Structure of Chlorodesoxypatulinic Acid
BERGEL et al.1 found that the product of the action of ethanolic hydrogen chloride on patulin gave on hydrolysis a crystalline chloro-acid, C7H7O4Cl, now called Chlorodesoxypatulinic acid. Afterwards, Plattner et al.2 observed that the same acid was readily produced by the action of hydrogen chloride on patulin in moist ethereal solution. The expression (I) was originally deduced1 for Chlorodesoxypatulinic acid from its relationship to patulin, for which the structure (II) was assumed3. Recent developments in this Laboratory and in that of Plattner necessitated the abandonment of these views, and led the Swiss group2 to formulate Chlorodesoxypatulinic acid as (III), which was consonant with either of two new structures, (IV)4 and (V)2, put forward for patulin in Cambridge and in Zurich, respectively. We have now accumulated new evidence which requires that (III) in its turn be rejected, and which leads to a new view of the structure of chlorodesoxypatulinic acid which is consistent only with the structure (IV) for patulin.
Robert Burns Woodward, 10 April 1917 - 8 July 1979
In his lifetime Robert Burns Woodward made outstanding contributions spanning almost the whole range of theoretical and experimental organic chemistry. In preparing this biographical memoir the authors were of the opinion that separation of biographical detail from a discussion of his scientific contributions would make for greater clarity in presentation. Accordingly the memoir is presented in two parts— a personal biography of R. B. Woodward (by A. R. T.) and a discussion of his scientific work (by J. W. C.).
A social analysis of the members of the Newfoundland House of Assembly, Executive Council, and Legislative Council for the period, 1855-1914
Chapter I consists of an introduction to the thesis, its purpose, and intent. Chapter II is an aggregate analysis of the members of the three chambers of government during the period 1855-1914. Chapter III is an analysis of geographic factors contributing to recruitment into Newfoundland politics. Chapter IV analyzes religion and its importance in Island politics. Chapter V studies occupation and class and Chapter VI is concerned with kinship and marriage. Chapter VII summarizes the findings of the previous chapters.
