摘要:
Reaction of 3-O-allyl glucose with [Ph3P)2RhCl]2 at temperatures below 60-degrees-C leads to isomerization of the double bond to form a vinyl ether. Reaction at temperatures above 100-degrees-C in N-methylpyrrolidone leads to formation of propyl and propenyl glucono-[1,4]-lactone derivatives, identified as their triacetates, as well as to a decarbonylated product.
