Asymmetric Synthesis of N-N Axially Chiral Compounds by Phase-Transfer-Catalyzed Alkylations

N-N axially chiral skeletons are significant structural motifs in natural products, pharmaceuticals, and functional materials. Herein we disclose a method for the asymmetric synthesis of N-N axially chiral compounds by phase-transfer catalysis. A wide range of N-N axially chiral quinazolinone derivatives were prepared in high yields with excellent stereoselectivities. Furthermore, the synthetic utility of the protocol was proved by large-scale reaction and transformation of the product. Density functional theory calculations provide insight into the mechanism.

Quinazolin-4-one derivatives

A medicament having an inhibitory activity against hematopoietic prostaglandin D2 synthase, which comprises as an active ingredient a compound represented by the following general formula (I) or a salt thereof: wherein X represents a group represented by the formula —N═C(R5)— or the formula —NH—CH(R5)—, R1, R2, R3, and R4 represent a hydrogen atom, a halogen atom, a C1 to C6 alkyl group, or a hydroxy group, R5 represents a C1 to C6 alkyl group or a C6 to C10 aryl group, and R represents an amino group.

A New Synthesis of 2-Aryl-3,4-dihydro-5H-1,3,4-benzotriazepin-5-ones

The reaction of 2-aryl-3,1-benzoxazine-4-ones (1) and hydrazine hydrate in refluxing xylene yields 2-aryl-3,4-dihydro-5H-1,3,4-benzotriazepin-5-ones in 55-74percent yield.In basic conditions this reaction, however, gives 2-aryl-3-aminoquinazolin-4(3H)-one
