• ; stabilizing factors; Introduction Oligosaccharide chains bearing α-ᴅ-galactofuranosyl (Galf) units are widely distributed in nature. Thus such compounds were discovered in fungi and yeasts [1][2][3], bacteria [4][5][6][7], brown and green seaweeds [8][9], lichens [10], and other species [11]. The presence of

• , the importance and quantification of the three stabilizing factors as well as the electronic structure of 2a have to await investigation by quantum chemical calculation. It seems appropriate in this context to have a look at the bonding situation of the corresponding sulfonyl lithio methanides 1

• ), there is no consensus regarding the number of bound water molecules and the location of their coordination. A number of intriguing questions remain: (1) Which localities of the host’s macrocycle are the strongest attractors for the guest water molecules? (2) What are the stabilizing factors for the
