Distannoxane-Catalyzed Conversion of Chiral Alcohol to N-[1-(1-Naphthyl)ethyl]carbamate

Difunctional distannoxanes, XR2SnOSnR2X

The difunctional distannoxanes, XR2SnOSnR2X, can be prepared by a number of different routes, and frequently turn up unexpectedly in reactions involving organotin compounds. They show a variety of (usually dimeric) structures, and are mild but effective catalysts for a variety of polar organic reactions. This article gives an overview of their chemistry.

One-pot synthesis of cinnamylamines with various protecting groups from cinnamyl ethers

The reaction of various alkyl cinnamyl ethers with CSI afforded the corresponding cinnamylamines with various protecting groups, such as -NHMoc, -NHiPoc, -NHCbz, -NHPnz, -NHTroc and -NHAloc. In the case of cinnamyl t-butyl ether and cinnamyl p-methoxybenzyl ether, the corresponding cinnamyl carbamates were formed via a different reaction pathway from the above.
