http://usefulchem-experiments1.blogspot.com/2006/05/exp-010.html
Useful Chem Experiments 1. Experimental details for the open source science project UsefulChem. Tuesday, May 23, 2006. To a catechol aldehyde. Using acid catalysis. How this fits into the synthesis of anti-malarials is described here. 303 mg, 1.653 mmol) was added to a 100mL round bottom flask that had a spout for a thermometer then added concentrated sulfuric acid (40mL). The solution was heated to an uncertain temperature with a reflux condensor for 14 hours under nitrogen. Stirrer stopped during the n...

Useful Chem Experiments 1. Experimental details for the open source science project UsefulChem. Sunday, July 09, 2006. Using acid catalysis. How this fits into the synthesis of anti-malarials is described here. Taken from Robbins (1965). A solution of adrenaline. TLC of 3:1 methylenechloride methanol. With iodine to stain. Solubility: good in methanol, poor in methylene chloride. Making 16B (note: the scale is way off). Li et al in 1998. Report the HMR for the target aldehyde (in DMSO-d6) as: 9.67(t,...

O blog tem como objetivo dar continuidade ao ambiente de sala de aula, onde todos possam participar, de forma interativa, dando suporte a educação em Química para o Ensino Médio. Nitrogênio é apontado como novo vilão do ecossistema. Mediada principalmente por bactérias que vivem em raízes de plantas leguminosas e no solo, a fixação do nitrogênio e outros componentes de seu ciclo mandam o elemento (em todas as suas formas) para a atmosfera, plantas, raízes subterrâneas e solos. Desde os tempos pré-biótico...

Useful Chem Experiments 1. Experimental details for the open source science project UsefulChem. Thursday, February 09, 2006. To test out the Ugi Synthesis and cyclization to a diketopiperazine using phenylacetaldehyde, methyl furfurylamine, N(tert-Butoxycarbonyl)L-methionine, and benzylisocyanide using the protocol described here. Is not predicted to be active but is a close analog of the product. That we wish to make once the catechol aldehyde. Is obtained. 2006-02-09. Based on the results of the TLC we...
