Many congratulations to Dr. Debgopal Jana (DEBGOPAL JANA) on the successful defense of your Ph.D. thesis! 🎉You have achieved a remarkable milestone in your academic journey. Wish you great success on your future endeavors!💥👏🎉

Our Org. Lett. cover story (Issue 49) highlights the mesmerizing 'Deep-Sea Domino Effect'—a six-step cascade reaction inspired by the ocean's mysteries, achieving the total synthesis of marine natural products (+)-brevianamides A & B. 🌊 Dive in! pubs.acs.org/toc/orlef7/26/… J Org Chem/Org Lett

It has been an incredible journey from Mr. to Dr. Pranay Shyamal .I am deeply grateful to my supervisor Prof. Alakesh Bisai for his unwavering guidance and support throughout this journey, as well as to the AB research group for their constant encouragement.

Huge congratulations to Rhituparna Nandi, Ranjit Murmu, Sreyashi Sadhukhan, Debopam Pal, Souvik Biswas, and Bishnu Das on their recent J Org Chem/Org Lett publication on "Total synthesis of Dixiamycins A & B via N−N bond formation using photoredox catalysis". pubs.acs.org/doi/10.1021/ac…

Happy to share our latest work published in JACS Au on the enantioselective total synthesis of Taiwaniadducts I, J & L, involving cycloadditions as a key strategy for constructing complex tetraterpenoids. Many congratulations to the team! Check this out: pubs.acs.org/doi/10.1021/ja…

A special moment in this achievement was having Prof. Tharmalingam Punniyamurthy as my external examiner. I extend my deepest gratitude to the AB Group members, most importantly, to my supervisor, Prof. Alakesh Bisai, whose guidance and support was the secret of my Phd Journey.

Heartiest congratulations to Dr. Mintu Da on being awarded the prestigious Marie Sklodowska-Curie Postdoctoral Fellowship 2024 at Queen Mary University, London! Well deserved!

A fascinating dive into Asymmetric Allylic Alkylation Chemistry by Prof. Stellios Arseniyadis ! Great to see Prof. Stolz Brian Stoltz and Alakesh Bisai Alakesh Bisai featured in his slides.

Check out the first total synthesis of brevianamide S. Congratulations Adam and the whole team! Spoiler: We didn't follow a biomimetic approach...we opted for a more flexible three-component coupling strategy. pubs.acs.org/doi/10.1021/ac…

Our latest #JOrgChem article presents the enantioselective total syntheses of anticancer agent nepetaefolin F and indolosesquiterpenoids, oridamycins A & B from a highly functionalized common intermediate. Many congratulations to the team! pubs.acs.org/doi/10.1021/ac…
