Stereoselective synthesis of branched cyclopentitols by titanium(III)-promoted reductive cyclization of 4-oxiranylaldehydes and 4-oxiranyl ketones derived from hexoses.
[摘要]:Titanocene chloride efficiently promotes the intramol. reductive cross coupling of highly functionalized 4-oxiranylaldehydes and 4-oxiranyl ketones derived from readily available hexoses affording branched cyclopentitols with good stereoselectivity.
