A chiral synthesis of pyrrolidine compounds en route to selective neuronal nitric oxide synthase inhibitors, and representative inhibitor compounds heretofore unattainable. The memory chip further has a first bit line coupled to the first FB DRAM cell, and a first state memory circuit coupled to the first bit line. The adapter can be used to prevent theft of exotic automobiles as well as their exotic steering wheels. The coarse estimation can then be followed by a fine estimation of the symbol rate and center frequency, using a bit tracking loop lock indicator.
