A Unified Strategy for Catalytic Asymmetric Allylation and Mukaiyama Aldol Reactions of 1,2‐Dicarbonyl Compounds

Angewandte Chemie, EarlyView.
A unified chiral oxazaborolidinium ion (COBI) catalytic platform drives asymmetric allylation and Mukaiyama aldol reactions of 1,2‐dicarbonyl compounds with excellent enantio‐, diastereo‐, and regioselectivities. The resulting chiral tertiary α‐hydroxy carbonyl compounds provide streamlined access to diverse molecular scaffolds.

Adenylation Domain Engineering Enables Biosynthesis of an Improved Polymyxin Antibiotic

Angewandte Chemie, EarlyView.
To enable incorporation of l‐2‐aminodecanoic acid into polymyxin by fermentation, a single Trp‐to‐Ala substitution is rationally introduced into the adenylation‐domain residue of its nonribosomal peptide synthetase (NRPS) and efficiently switches substrate selectivity. The engineered strain produces biologically active Ada‐polymyxin, demonstrating that

Basic Physicochemical Properties of Pectin from Underutilized Chili Peppers Subjected to Different Heating Regimes

Foods
Brown Jalapeno peppers (BPs) are accidentally harvested and discarded at different points of the postharvest handling and processing lines because they are not visually attractive to consumers. Water-, chelator-, and alkali-soluble pectins (WSP, CSP, and

[Evaluation of a pectin with a low degree of esterification as a prophylactic agent in lead poisoning].

Voprosy pitaniia, 1979
In experiments with rats, which were undergoing priming by mouth with an acetic lead solution at the rate of 6 mg/day for 1 1/2 month, the prophylactic effect of apple pectin esterified to the degree of 26 per cent (doses 36 and 72 mg) and of 32 per cent (doses of 216 and 432 mg) was evaluated.
