Abstract
Molecular and supramolecular logic gates are candidates for computation at the nanoscale level. Nowadays all common logic operations can be mimicked with molecular devices based on chemical approaches. One step further towards molecular systems with increased logic capabilities is the addition or subtraction of binary digits. This Minireview describes recent developments to attain this goal, including bioinspired systems based on DNA and enzymes. Furthermore, chemical molecular logic gates are discussed and compared critically with regard to alternative concepts.

Abstract
[Structure: see text] The asymmetric synthesis of a highly functionalized tetrahydroisoquinoline relevant to the total synthesis of Et-743 is described. The key step involves a highly diastereoselective radical cyclization on a glyoxalimine derivative.
