TL;DR: In this paper, anantiomerically pure undecose acetonide 9 was synthetized through heptose intermediate 5, starting with D-glyceraldehyde acetonides (1), and the key steps were two consecutive four-carbon homologations.
Abstract: Enantiomerically pure undecose acetonide 9 was synthetized, through heptose intermediate 5, starting with D-glyceraldehyde acetonide (1). The key steps were two consecutive four-carbon homologations, each consisting of four reactions: (i) stereoselective elongation of the aldehyde precursor with 2-(trimethylsiloxy)furan, giving C n+4 butenolide templates, (ii) anti-selective cis-dihydroxylation of the butenolide double bond, giving fully functionalized lactones, (iii) lactone ring opening and protection, giving open-chain methyl esters and (iv) DIBAL reduction to aldoses 5 and 9

07 Nov 1983TL;DR: In this article, an 8-substituted guanine derivative bonded 9-1' to an aldose having 5 or 6 carbon atoms in the aldoses chain was used as an active agent.
Abstract: Compositions and methods for their use in modulating animal cellular responses are disclosed. The compositions include as an active agent an effective amount of an 8-substituted guanine derivative bonded 9-1' to an aldose having 5 or 6 carbon atoms in the aldose chain. The composition includes a diluent amount of a physiologically tolerable carrier. The guanine derivative is free of electrically charged functionality, while the 8-substituent has an electron withdrawing inductive effect greater than that of hydrogen and contains fewer than about 15 atoms. Animal cellular responses are modulated by contacting the cells with a composition of this invention.
