摘要:This invention relates to an efficient and enantioselective synthesis of the spiro-compounds of formula (1) as common intermediate, featuring an asymmetric introduction of the all-carbon quaternary centre in high selectivity and a very efficient one-pot procedure for the C2 elongation to generate the spiro-structure.For the all-carbon quaternary centre, a Tsuji-Trost asymmetric allylic alkylation (AAA) process was designed to develop a sustainable procedure with very low catalyst loading, thereby also facilitating the Pd content control in the product, under practically solvent free conditions. Furthermore, multiple synthetic transformations in a one-pot procedure were implemented by using a one-pot procedure either in form of a three-transformation sequence comprising Hydroboration-Alkylation-Dieckmann Condensation to compound of formula (1) or in form of a five-transformation sequence comprising Hydroboration-Alkylation-Dieckmann Condensation-Hydrolysis-Decarboxylation to compound of formula (9).

摘要:Disclosed are a deuterated compound of formula (I), or a salt thereof, and methods for preparation thereof. The present disclosure may provide a mild, versatile organophotoredox method for the preparation of diverse, enantioenriched α-deuterated α-amino acids. In particular, the present disclosure may address the long-standing challenge of installing sterically demanding side chains into α-amino acids, including late-stage modifications on medicinal agents and natural products.
