Stereoselective Chemoenzymatic Synthesis Metaraminol Involving Gold‐Catalysed Alkyne Hydration and Carbonyl Biotransamination

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A chemoenzymatic synthesis of (1R,2S)‐metaraminol was developed by combining gold(I)‐catalysed alkyne hydration and stereoselective biotransamination in a sequential one‐pot process. Various phenol protection strategies were considered in oxidation‐reduction sequences, providing access to enantiopure propargylic alcohols as starting materials for ...

High Relative Accuracy Computations With Covariance Matrices of Order Statistics

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In many statistical applications, numerical computations with covariance matrices need to be performed. The error made when performing such numerical computations increases with the condition number of the covariance matrix, which is related to the number of variables and the strength of the correlation between the variables. In a recent work,
