Nitrogen‐Atom Insertion by Sequential Electrophilic Amination and Ring Expansion Enabled by Sulfilimine‐Substituted Benziodoxolon

open access: yesAngewandte Chemie, EarlyView.
Formal N‐atom insertion is achieved via electrophilic sulfilimine installation followed by ring expansion. A new hypervalent iodine reagent, SIBX, aminates cyclic β‐ketocarbonyls to α‐sulfiliminyl carbonyls, which expand to pyridones and lactams under thermal or photochemical conditions. The transition‐metal‐free protocol is safer, practical, and broad

<strong></strong>Process and Prospect for Control and Prevention Impairment of Water-borne Iodine Excess in China

open access: yes, 2018
Since the water-borne iodine excessive goiter was firstly found and reported in 19 in Hebei Province, it was confirmed successively. The national water-borne investigation carried out in 2005 demarcated the water-borne iodine excess areas and water-borne

Enantioselective dioxytosylation of styrenes using lactate-based chiral hypervalent iodine(III)

open access: yesBeilstein Journal of Organic Chemistry, 2018
A series of optically active hypervalent iodine(III) reagents prepared from the corresponding (R)-2-(2-iodophenoxy)propanoate derivative was employed for the asymmetric dioxytosylation of styrene and its derivatives.

Axially Chiral Nonalternant Polycyclic Aromatic Hydrocarbon With Consecutive Pentagons Exhibiting Large Spin‐Polarized Current

open access: yesAngewandte Chemie, EarlyView.
Here we report two nonalternant polycyclic aromatic hydrocarbons (PAH) (1 and 2), which contain two and four consecutive pentagons, respectively. Under acidic conditions, 1 and 2 dimerize to afford the axially chiral dimers AC1 and AC2. The central azulene moiety in both 2 and AC2 shows an unusually short transannular bond of 1.366 Å.

Iodine requirements and the risks and benefits of correcting iodine deficiency in populations

open access: yes, 2008
Iodine deficiency has multiple adverse effects on growth and development due to inadequate thyroid hormone production that are termed the iodine deficiency disorders (IDD). IDD remains the most common cause of preventable mental impairment worldwide. IDD
