4. API PROJECTS WORKED
Chemistry subject matter expert
I am working as a team leader for a group of 5 members and we are working for the
generation of chemistry research database. My job is to validate the data done by my
group members.
Tenofovir Alefanamide Hemi-Fumarate (anti-retroviral)
I have worked on the process development of tenofovir alefanamide hemi-fumarate. In
this process we have developed a catalyst/ligand free approach which will selectively
give 90 % pure diastereomeric isomer and <10 % of undesired isomer which further
removed during crystallization. In this project we faced problem in isolating hemi-
fumarate form still process are ongoing to get desired hemi-fumarate form.
Anacetrapib
Completed the process development of Anacetrapib (anti-cholesterol).
In this project we avoided the formation desmethyl API impurity by modified process
development to eliminate the impurity completely compared to innovator method. We
achieved 80% overall yield which is 10% more yield compared to other competitors.
Sunitinib & Valsartan
I worked on the process development of Sunitinib and Valsartan during my research
experience on Cadila pharmaceuticals. Our research group successfully carried out
technology transfer and process development on these molecules before the time line.
Donepezil Hydrochloride
In this project I carried out novel route for the formation of piperidone epoxide a key
intermediate for the formation of API which yielded one process patent in this molecule.
Similarly worked on the process development of Gemcitabine, Ezetimibe,
Temozolomide, Montelukest in Cipla pharmaceuticals.

6. DOCTORAL RESEARCH SUMMARY
In order to form C2 symmetric macrodiolide the required alkyne / alkene tethered diazocarbonyl
compounds 5 were assembled in a step-wise manner. Tandem reaction of -diazocarbonyl
compounds in the presence of rhodium(II) acetate catalyst was demonstrated to furnish
wide range of conformationally restricted C2 symmetric macrodiolides via head to tail
dimerization of carbonyl ylides.

A series of bis-diazocarbonyl compounds 8 were assembled from transesterification reaction of
active methylene 3 with dihydroxy compounds in dry toluene followed by diazo transfer
reaction. Macrodiolides 11/12 incorporating oxa- and dioxa-fused units were synthesized from
bis-diazocarbonyl compounds 8 and bis-aldehyde / bis-olefin 9/10 as precursors to utilize the
bis-cycloaddition approach. Bis-olefin compounds 10 were obtained via Wittig reaction of the
corresponding bis-aldehydes 9. Initially, the reaction of bis-diazocarbonyl compounds 8 with
DMAD / NPM / aldehydes in the presence of rhodium(II) acetate dimer furnished bis-
cycloadduct 13-15.

8. Reaction of diazoamide 27 was treated with 1 equiv of Grignard reagents to give hydrazone
incorporating oxindole 28 in excellent yield. Similar reaction was performed with diazoester 33
and cyclohexanone diazo compounds 31 to furnish 34/32. Thus, the diazoamide 27 was treated
with 2.5 equiv. Grignard reagents to furnish 2-phenyl-3-azoindole derivative 29 in excellent
yield. Reduction of azo compounds 29 carried out using SnCl2 in AcOH to their respective
amino compounds 30.
