In this paper, we present the phospholipidosis-inducing potential (PLIP) of forty fragment-sized diamines derived from N-benzyl-4-(methylamino)piperidine and discuss the relationship between their PLIP and the physicochemical properties. Our results demonstrate that the previously reported methods are not suitable for predicting the PLIP of fragment-sized diamines; the second basic pKa can distinguish PLIP-positive diamines from PLIP-negative diamines more accurately than ClogP or most basic pKa. To the best of our knowledge, this is the first report describing the relationship between PLIP and second basic pKa.

Distinct chemoselectivities in the platinum-catalyzed 1,2- carboalkoxylations of 5-alkoxypent-1-yn-3-ol derivatives

Two distinct Pt-catalyzed carboalkoxylations of alkynes are reported. The cycloisomerization of 5-alkoxypent-1-yn-3-ol derivatives 5 produces 2,6-dioxabicyclo[3.1.0]hexanes 6; the mechanism is postulated to involve a hydroxyl-triggered [3.3]-sigmatropic a

Conformational analysis of oligo-1,3-dioxanylmethanes

Stereoselective synthesis of a series of 1,3-dioxan-4-ylmethanes 1-9 has been achieved by use of solely substrate-based asymmetric induction. The simple C2-symmetric bis(dioxanyl)methane 1 has a greater than 99% conformational preference at the two inter-ring bonds for the conformation 1a. The homologous structures 3-9 contain up to five dioxanylmethane units, maintaining a high conformational preference in each of the bis(dioxanyl)methane units. Thus, these flexible compounds reach a conformational preference in excess of 90% over up to eight rotatable interring bonds. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.
