Reductive Amination/Cyclization of Methyl Levulinate with Aspartic Acid: Towards Renewable Polyesters with a Pendant Lactam Unit

We can restrict our attention to the case when G is of constant type (recall that the type is a locally constant function on S); this implies that there exists a Chevalley Z

In the competing acylation step, Ldt fm was initially fully acylated by nitrocefin but imipenem gradually replaced nitrocefin in the enzyme active site since the acylation

In summary, this contribution described a switchable and efficient iron catalysed synthesis of N- substituted pyrrolidinones and pyrrolidines starting from levulinic acid

Indeed, as can be seen in Figure 3 (and with the manipulation of the optimized geometry files provided as supporting information), the introduction of a para-substituted

The main theorem of this PhD thesis states the following: the genus 0 coefficients of the quantum Witten- Kontsevich series defined by Buryak, Dubrovin, Guéré, and Rossi are equal

In the words of the 1987 Manifesto, "We will therefore support the co-existence of a variety of schools - comprehensive, grammar, secondary modem,

Herein, we report an iron-catalysed efficient and selective one-pot preparation of N-substituted cyclic amines (including pyrrolidines, piperidines and azepanes)

10 Inspired by the successful examples on the enantioselective addition to oxocarbenium ions and in continuation of our interest in the Prins cyclization reaction, 11 we
