The catalytic enantioselective 6-exo-trig Michael addition-lactonization of enone-acid substrates to form cis-chromenones with high diastereo- and enantiocontrol was developed using the commercially available isothiourea tetramisole. An acidic workup prov
The 2-(allyloxy) phenyl acetyl ester as a new relay protecting group for oligosaccharide synthesis
Arranz, Esther,Boons, Geert-Jan
, p. 6469 - 6471 (2007/10/03)
The 2-(allyloxy) phenyl acetyl group can be removed by a relay approach using Pd(PPh3)4 in combination with proton sponge, conditions that do not affect acetyl, benzoyl and levulinoyl esters. On the other hand, the acetyl and levulin
