Novel cyclic and acyclic oxazaphospholanes are described, as well as their use in the synthesis of sphingomyelin and sphingomyelin analogous. A logic network is arranged with the buffer elements to form functional paths, a test unit is structured and arranged to test the functional paths and to be coupled to the control lines, and a configuration storage register to set the selected one of the buffer driver and bypass for each passing functional path. 5V is applied to the selected gate line respectively.
