Temozolomide- Mr kiss kiss bang bang

It’s not often that drug molecules find themselves on the reagent shelf alongside materials that may have been used to assemble them. The prince and the pauper so to speak. In 2019 Paul Hergenrother from the University of Illinois published a paper in Angewandte Chemie claiming a diazomethane surrogate that was a commercially available, weighable, solid:

Veni Vidi Vici (I came, I saw, I conquered)

A couple of interesting papers published recently on aryl iodination. I sure I don’t need to reiterate how useful iodinated intermediates are in synthesis- most significantly their heightened reactivity in metal catalysed cross coupling chemistry,1 and, more recently their application as organocatalysts in hypervalent iodine chemistry.2 As is common in synthetic science, the intermediates you

The scheme below shows the synthesis of a late-stage intermediate towards AZD9833, a compound identified by AstraZeneca as a selective estrogen receptor degrader (SERD) and antagonist that is currently in phase 2b clinical trials for the treatment of ER+ breast cancer. Can you identify reagents or intermediates A, B and C? Answers and a reference

Identify the reagents 3: answers

Last month I posted a scheme from showing Oppolzer’s synthesis of racemic Lysergic acid and asked if you could identify reagents or intermediates G, I, and H. Below are the answers! You can read more here in the full reference: W. Oppolzer et al, Helv. Chim. Acta 1981, 64, 478–481
