[GRAPHICS]Recent efforts in our laboratories have resulted in a synthetic approach toward C2'-alkylated K252a analogues via extension of a K252a cyclofuranosylation strategy. The bis-indole-N-glycosidic coupling of 6-N-(3,4-dimethoxybenzyl)-staurosporinone (21) with a number of highly functionalized carbohydrates has given access to previously unattainable, biologically relevant analogues.
Secondary Allyltitanium(IV) Reagents in Aldehyde Allylation I: Extension of the Hoppe Reaction to γ-Alkoxy Secondary Allyl Carbamates
An efficientaccess to optically active (R)- or (S)-γ-alkoxy allyltitanium(IV) intermediates, in aldehyde allylation reactions, is described. Enantiomeric γ-alkoxy secondary allyl carbamates (R)- and (S)-14 were first prepared. Determination of their enantiomeric excess was realised on the corresponding deuterated isotopic derivatives by NMR in chiral liquid media. Subsequent aldehyde allylation reaction
