Photoassisted access to enantiopure conformationally locked ribofuranosylamines spiro-linked to oxazolidino-diketopiperazines.

ABSTRACT: N-Furoylated L-threonine-, serine-, or cysteine-based aminoacetals are coupled with o-aminoketones or aldehydes to offer rapid access to diverse enantiopure polyheterocycles possessing conformationally locked aminoglycoside-containing molecular scaffolds. The key step involves photogeneration of azaxylylenes which undergo [4 + 4] or [4 + 2] cycloadditions to the tethered furoyl pendants.
