Abstract

Part I - 2-Deoxy-DL-ribose. Synthetic routes to 2-deoxy-DL-ribose from non-carbohydrate precursors have been investigated and an eight stage synthesis from propargyl alcohol is described. Kojic acid has been elaborated, via a known intermediate, to 2-deoxy-DL-ribose. As an extension of this work a route to the 2,6-dideoxyhexoses from acetylenic precursors is described. Appendix I. The selective addition of hypobromous acid to hex-5-en-2-yn-1-ol is discussed. Appendix II. Some unsuccessful approaches to DL-ribulose from acetylenic precursors have been explored. Part II - Apiose and Cordycepose. A wide variety of synthetic approaches to the branched-chain sugars apiose and cordycepose, from non-carbohydrate precursors, has been studied. The synthesis of 2-phenyl-5-carboxy-1,3-dioxan, a derivative of the saccharinic acid, 4-hydroxy-3-hydroxymethyl propanoic acid which has not hitherto been synthesised, is described. Part III - Rhodosamine. Routes to the amino-sugar rhodosamine from acetylenic precursors are described. An approach from hept-1-en-4-yn-6-ol has given a compound with the gross structure of DL-aldehydo "rhodosamine" diacetate. Anomalous oxidation of an intermediate amine is discussed in the light of recent investigations.
