Stereodivergent synthesis of lipophilic α-amino acids and 3-amino-1,2-diols
摘要:
A stereodivergent protocol for the synthesis of both enantiomers of some lipophilic alpha-amino acids and diastereomeric 3-amino-1,2-diol derivatives related to sphingoids has been developed from a common source using sequential applications of diastereoselective allylation of a alpha-chiral imine and cross metathesis as key steps.

Disclosed are compounds having polybasic functionalities. The compounds inhibit bacterial efflux pump inhibitors and are used in combination with an anti-bacterial agent to treat or prevent bacterial infections. These combinations can be effective against bacterial infections that have developed resistance to anti-bacterial agents through an efflux pump mechanism.
