A Study of the Active Esters of the Steroisomeric Mucic Acids in Relation to the Law of Optical Superposition

Lapsley, Robert William (1940) A Study of the Active Esters of the Steroisomeric Mucic Acids in Relation to the Law of Optical Superposition. PhD thesis, University of Glasgow.

Abstract

(1) Allomucic acid has been prepared from mucic acid and characterised. It has been found by Professor Posternak to be identical with his synthetic allomucic acid. (2) dl-Talomucic has been shown to rearrange in acetic anhydride to mucic acid and allomucic acid. A simple route is possibly available for synthesis of the ribose type of sugar structure. (3) The specific rotations of the 1-menthyl esters of tetra-acetyl mucic and tetra-acetyl allomucic acids have been compared. The specific rotations are not in agreement with van't Hoff's law of Optical Superposition. Additional Paper. (1) A synthetic route to 2.3.4.7-tetra methoxy 9 methyl phenanthrene has been extensively explored. (2) The stability of N-acetyl colchinol methyl ether to dehydrogenation has been further investigated and found to be in agreement with previous work. (3) Preliminary work on the synthesis of 2.3.4.6-tetra methoxy 9 methyl phenanthrene has been carried out. (4) Preliminary work has also been done on the synthesis of a possible simple analogue of colchinol methyl ether.
