A rapid access to the spiroaminoketal framework

A convergent and stereoselective synthesis of 1-oxa-7-azaspiro[5.5]undecane is described. This functional new spiroheterocycle is readily available from acetone N,N-dimethylhydrazone via a double alkylation and subsequent spiroannulation process. Georg Thieme Verlag Stuttgart.

Orthogonally protected glycerols and 2-aminodiols: Useful building blocks in heterocyclic chemistry

The efficient synthesis of orthogonally protected glycerols, 2-aminopropane-1,3-diols and 2-aminobutane-1,4-diols that can constitute useful tools in heterocyclic chemistry, is reported. These interesting tri-functionalized small synthons were easily prepared from serine or aspartic acid. In addition, these substrates can be readily transformed into their iodide derivatives in very good yields. ARKAT USA, Inc.
