Article Synopsis
- Cor triatriatum dexter (CTD) is a rare heart condition affecting less than 0.4% of the population, characterized by an unusual division in the right atrium due to an embryonic valve.
- A case study detailed a 7-day-old newborn who experienced cyanosis when feeding or crying; CTD was diagnosed through echocardiography and confirmed with cardiac MRI.
- The newborn underwent successful surgery at 14 days old, showcasing the importance of early diagnosis and intervention to prevent complications and improve outcomes.
Herein we report for the first time the diastereoselective synthesis of (2,3a,7a)- and (2,3a,7a)-octahydroindole-2-phosphonic acid (Oic -fused stereoisomers) from diethyl ()- and ()-phosphopyroglutamate derivative. The key steps of this procedure are the ruthenium tetroxide oxidation of enantiomerically pure diethyl ()- and ()-phosphoprolinate obtained through Katritzky's benzotriazole-oxazolidine methodology, a highly diastereoselective successive double 4,5-diallylation of diethyl ()- and ()-phosphopyroglutamate with allyl bromide and allyltrimethylsilane with a -addition mode, and a ring-closing metathesis with Grubbs' first-generation ruthenium catalyst.

- Scientists found a special treatment that helps cells change to a flexible state, which is important for healing injuries in muscles.
- This treatment uses certain chemicals that help muscle cells heal better and faster, even in old mice.
- The research suggests this method might be a good way to help with healing injuries and could be easier to use than changing genes.
Objective: Describe the measurements of systolic, diastolic and mean blood pressure in healthy term and late preterm newborns to establish normal values.
Methods: Cross-sectional study carried out in the nursery of the Hospital Español, located in Mexico City. A sample of 551 healthy newborns were included in the study.
Palladium-catalyzed functionalization was presently performed on two building blocks: 4-oxazolin-2-ones and 4-methylene-2-oxazolidinones. Direct Heck arylation of 4-oxazolin-2-ones led to a series of 5-aryl-4-oxazolin-2-ones, including analogues with N-chiral auxiliary, in an almost quantitative yield. The Pd(II)-catalyzed homocoupling reaction of 4-oxazolin-2-ones provided novel heterocyclic across-ring dienes.
