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.

Enantiospecific Synthesis of (3 R,4 R)-1-Benzyl-4-fluoropyrrolidin-3-amine Utilizing a Burgess-Type Transformation

Manufacture of an EGFR inhibitor required the asymmetric synthesis of a key 3,4-trans-substituted pyrrolidine suitable for pilot-plant scale. The initial synthetic route utilized reagents and intermediates that posed safety concerns due to their energetic potential and then required supercritical fluid chromatography to access the desired single enantiomer. Burgess-type reagents provide tremendous utility in organic synthesis but see limited use on large scales because of their high cost and instability. Nevertheless, extensive process development led to a scale-friendly process where in situ formation of a Boc-Burgess reagent enabled access to a chiral cyclic sulfamate from inexpensive materials. ReactIR monitoring was used to study intermediate stability and enabled processing on a multikilogram scale. The sulfamate was converted to trans-3-fluoro-4-aminopyrrolidine 1 with complete stereospecificity. Intermediate crystallinity offered purity control points where byproducts and impurities were rejected, avoiding the need for chromatography.
