@Palani_IISc @iiscbangalore Congratulations!!!

Hello everyone, I have officially joined twitter and wanted my first post to be a special one! On that note, I am excited to share that I'll be joining the Department of Organic Chemistry @iiscbangalore as an Assistant Professor starting this week!

#TotalSynthesis of Altemicidin: A Surprise Ending for a Monoterpene Alkaloid by @ClaireMagnani, @joserhern1, Dean J. Tantillo, and Thomas J. Maimone at @UCB_Chemistry in @JACS_Au pubs.acs.org/doi/full/10.10…

Congrats @ClaireMagnani on another success! Read in @JACS_Au Total Synthesis of Altemicidin: A Surprise Ending for a Monoterpene Alkaloid | JACS Au pubs.acs.org/doi/10.1021/ja…

Excited to see part of my work from when I was an @Amgen Scholar at @UCBerkeley published! Nature and chemists continue to impress me with their synthetic prowess, especially when their strategies converge! pubs.acs.org/doi/abs/10.102…

🏆🏆Congratulations to Professor Tom Maimone on being named a recipient of the 2024 Tetrahedron Young Investigator Award. Tom was honored for his work in Organic Synthesis. For more information see: sciencedirect.com/journal/tetrah…

Enantioselective #TotalSynthesis of (−)-Caulamidine A by @ZhouyangZhu and Thomas J. Maimone at @UCB_Chemistry in @J_A_C_S pubs.acs.org/doi/10.1021/ja…

Go Toby!

@Chemjobber Haven’t seen any updates for industry jobs in awhile….asking for a friend.

There are already five positions lined up for the Fall 2024 market, list to go live on June 1 twitter.com/LeitchLab/stat…

@petri_yana Congrats!

Our purely chemical approach (shout-out to my wonderful collaborator Clair Gutierrez from the Raines lab) for turning proteins “ON” and “OFF” is finally out! The generality of this strategy was highlighted with three examples - lysozyme, cytochrome c, and HIV protease!

The 2023 edition of Heterocycles is coming on April 3 (see attached syllabus)! This year will be a reverse classroom format wherein new material will be discussed with problem solving sessions including real-world consulting questions. Please review the 2021 lectures on our YouTube channel (bit.ly/3yYyABB) before attending to maximize learning outcomes. Primary textbook available here: books.apple.com/us/book/the-po…. Outside participants are welcome to join over Zoom. As in previous years, those from industry are encouraged to send their problems in advance (after scrubbing IP) for us to solve during class. Please contact Brendyn Smith for the Zoom link (smithb@scripps.edu) and any other questions you may have.

The synthesis features a number of unusual maneuvers, all confirmed by X-ray crystallography.

Got Nitrogen? A concise enantioselective synthesis of the marine-derived alkaloid KB343 is disclosed today in @ChemRxiv: bit.ly/3SoRMkQ.

Our valentine this year is the N-alkylated azole motif! Check out our strategy to alkylating azoles with abundant C–H precursors in @J_A_C_S #azolemyheart pubs.acs.org/doi/10.1021/ja…

@RealSkipBayless Go to bed skeletor

How fortunate was Aaron Rodgers with that illegal hands to face penalty negating yet another big-game Rodgers interception?

@JJWatt You were the best boyfriend I never had ❤️

Sometime in the coming days I’ll find the right words. But for right now, all I can say is thank you. You’ve changed my life forever and I am perpetually grateful. 🙏🏼

@mevans86 My issue is with the yields! Check the equivalents for each class of substrate!

Fantastic! Except it's a benzylic hydroxylation; instead of colored circles, they should've used "Ar." Yes, I went there. Sorry not sorry.

@ClaireMagnani @femipv @Momademia He’s already a grad student

@femipv @Momademia Some days my 2 yo old eats mushroom risotto or veggie lentil soup and then there is today where he ate french fries and pita bread for lunch🤷‍♀️

Parents, how do you keep your cool when your child rejects every damn fancy meal that you took an hour or more to prepare? @Momademia

@GavinNewsom Nice virtue signal. What are you doing to ameliorate the current UC graduate student strike?

Still waiting on the Florida Governor to reject the endorsement of a neo-nazi, white supremacist.

What is this shitty not-flu, not-covid, not-RSV thing going around?? It has taken out my team at work one by one and both kids poorly now. I had it two weeks ago. Felt bloody awful. Making people get tracheitis, febrile, sore throat. Any virologists know? Paraflu?
