Disclosed are linear discrete PEG constructs, which can be created and produced in a precise and reproducible way. Key to being able to do these things, where x in the discrete PEGX can vary from about 2 to about 64, is that the processes used to make each linear portion is controlled to give essentially one oligomer/one compound. Having a variable length linear discrete PEG construct that is (a) primarily an linear discrete PEG construct with diagnostic or therapeutic groups attached along a chain of attachment cores, which is attached to a preferential locator; (b) is an m-discrete PEG as the terminal construct on the linear portion, and "hidden"; (c) or linear discrete PEG with a terminus group that can be either negatively or positively charged, or neutral; and any of the discrete PEG portions can be designed to be cleaved after entering the cell.

atom-economic catalytic method for asymmetric α-allylation of N-unprotected amino esters was achieved to provide enantioenriched α-quaternary α-allyl amino esters with high yields and high enantioselectivities. To achieve this transformation, we utilized a ternary catalytic system consisting of a chiral phosphoramidite-palladium complex, an achiral picolinaldehyde, and the Lewis acid Zn(OTf)2.
