## Abstract Arcyriacyanin A (1) has been synthesized by three different routes. In the first synthesis the bisbromomagnesium salt of 2,4β²βbiindole (5) was treated with dibromomaleimide (6) to yield arcyriacyanin A (1). The second approach used an intramolecular Heck reaction for the cyclization of

'Lhe solution of the perennial problem of human relations is to be found rooted in an understanding of the nervous system, for behavior is the reaction of a living organism to the coordinated, correlated, and integrated stimuli resulting from changes in the physical and chemical environment. This is made possible by the structure and function of the organized nervous system. The energy required to make adjustment possible is, needless to say, derived from the incredibly complex chemical activity of protoplasm, but the direction in which that energy flows, and the way in which it is used, is a consequence of the pattern of organization of neural tissue. It is not enough, therefore, to know the details of the complex structures involved, but rather to have some over-all grasp and understanding of the way the nervous system works. Analysis of the units is of vital importance even down to the sub-microscopic level, but equally important is a grasp of the inter-relatednesses of all component parts. Moreover, since behavior is in part the result of the impact of one organism on another, no real picture of the forces which make man do what he does is possible without a complete lmomledge and understanding of the structure and function of the nervous system.

Water soluble carbohydrates were studied at various developmental stages in the cellular slime mold, Dictyostelium discoideum. The only water soluble sugars found were, the non-reducing disaccharide, trehalose and glucose. The level of trehalose varied very dramatically during the life cycle. Throug
