divergent strategy for the synthesis of multisubstituted tetrahydrofurans and pyrrolidines, starting from easily accessible β‐hydroxyketones or β‐aminoketones to react with diazo compounds. Under RhII catalysis, this transformation is proposed to proceed through a metal–carbene‐induced oxonium ylide or ammonium ylide formation followed by an intramolecular aldol‐type trapping of these active intermediates
The present invention relates to inhibitors of the enzyme TRMT2A and medical uses thereof. More particularly, the present invention relates to the treatment and the prevention of polyglutamine diseases using TRMT2A inhibitors.

A general and efficient aza-Michael reaction promoted by aqueous sodium carbonate solution has been developed. The reaction has complete mono-alkylation selectivity and proceeds with complete chirality retention for chiral amino esters. With a broad substrate scope, a well-common catalyst and simple operation, the catalytic approach provides a facile, practicable, economical, and environmentally benign method for the synthesis of beta-amino carbonyl compounds.
