Selective deprotective method using palladium-water soluble catalysts

Allylcarboxy and Allyloxycarbonyl groups can be removed without affecting dimethylallylcarboxy and cinnamylcarboxy groups in the same molecule, using Pd(0) water soluble catalyst prepared in situ, with diethylamine as allyl scavenger. Homogeneous or biphasic media are suitable; the yields of deprotection are quantitative.
