Title:
METHOD FOR PRODUCING BICYCLIC ULOSONIC ACID DERIVATIVE AND METHOD FOR PRODUCING ULOSONIC ACID DERIVATIVE
Document Type and Number:
Japanese Patent JP2020158489
Kind Code:
A
Abstract:
To provide a bicyclic ulosonic acid derivative and a method for producing an ulosonic acid derivative, with which the intended bicyclic ulosonic acid derivative and the ulosonic acid derivative of α-form which has a specifically high α-selectivity to various substrates (nucleophiles) may be obtained at a high yield.SOLUTION: The method for producing a bicyclic ulosonic acid derivative includes a α-bond forming step, in which C1 and C5 positions of ulosonic acids having a cyclic structure is cross-linked with a cross-linking group so that 1, 4 -cis bicyclic ulosonic acid electrophile in which the β-plane is shielded is reacted with a nucleophile, resulting in that the nucleophile is bonded to the C2 position of the bicyclic ulosonic acid electrophile so as to synthesize a bicyclic ulosonic acid derivative.SELECTED DRAWING: None
