The synthesis of spirocyclic amideacetals (33–93 %) has been achieved through Ru(II)-catalyzed condensations of N-carbamate protected pyrrolidinones with metal carbenes derived from α-diazo-β-ketoesters. Thanks to the mildness of the diazo decomposition conditions induced by a 1 : 1 combination of [CpRu(MeCN)3][BArF] and 1,10-phenanthroline, the formation of the sensitive products is possible. Full

A transdermal drug delivery composition comprises an acrylate copolymer and from about 8% to about 30% by weight fentanyl. A transdermal fentanyl delivery composition comprising methyl laurate or tetraglycol as a permeation enhancer is also provided. The transdermal drug delivery compositions can be used to make a transdermal drug delivery device for the delivery of fentanyl.
The invention relates to compounds of formula (I) or a pharmaceutically acceptable solvate or salt thereof, including a solvate of such a salt, wherein R
