Syntheses of the chromomycinone (cas 10183-93-4) side chain from carbohydrate precursors

Add time:07/20/2019    Source:sciencedirect.com

Appropriate dithiane derivatives of D-threo configuration were prepared starting with D-arabinose and D-galactose, respectively. Their dianions served for nucleophilic additions to model aldehydes, thus comprising syntheses of the complex side chain of chromomycinone (cas 10183-93-4). In contrast to former reports a trianion formation of a dithiane-blocked α,β-dihydroxy aldehyde could not be confirmed.
