Programmable One-Pot Oligosaccharide Synthesis
Journal of the American Chemical Society, 1999The reactivity of a number of p-methylphenyl thioglycoside (STol) donors which are either fully protected or have one hydroxyl group exposed has been quantitatively determined by HPLC in conjunction with the development of a broadly applicable approach for a facile one-pot synthesis of oligosaccharides.

One-Pot Synthesis of Rufloxacin
Synthetic Communications, 1991Abstract Rufloxacin (MF-934) was prepared in one-pot synthesis in 61% yield by treatment of the 2,3,5-trifluoro-4-(4-methyl-1-piperazinyl)-benzoyl acetate, first with N,N-dimethylformamide dimethyl acetal, then with 2-aminoethanethiol, followed by cyclization and hydrolysis.

Selective “One-Pot” Synthesis of Functionalized Cyclopentenones
The Journal of Organic Chemistry, 2012Double addition (1,2-1,4) of vinyl magnesium bromide to squaric acid derivatives allows the preparation of polyoxygenated cyclopentenones (8) in a "one-pot" procedure. The reaction occurs through the intermediate formation of octatetraenes (6). Protonation of this latter intermediate at -78 °C with TFE occurs selectively at the vinyl CH(2) closer to ...

One‐Pot Sequence‐Controlled Synthesis of Oligosiloxanes
Angewandte Chemie International Edition, 2018AbstractSilicones (organopolysiloxanes) have found applications in a wide range of research areas, and their unique and valuable properties have rendered these materials virtually irreplaceable. Despite the fact that silicones have been employed industrially for more than 70 years, synthetic routes to generate silicones remain limited, and the sequence‐

One-Pot Synthesis of Chiral Nonracemic Amines
The Journal of Organic Chemistry, 2011One-pot five-component reactions of oxathiazolidine-S-oxides with mesitylmagnesium bromide, lithium bis(trimethylsilyl)amide, aldehydes and Grignard reagents afford chiral nonracemic amines or sulfinamides in good yields and high stereoselectivities.

One-pot synthesis of cyclic antifreeze glycopeptides
Chemical Communications, 2009The first cyclic glycopeptides exhibiting significant antifreeze activity by forming hexagonal-bipyramidal ice crystals, denoted cyclic antifreeze glycopeptides (cyclic AFGPs), were constructed by a one-pot synthesis based on the controlled cyclization reaction of pre-formed small linear glycopeptides.

A New One-Pot Synthesis of Alkynylphosphonates
Organic Letters, 2000A method for the palladium-catalyzed synthesis of alkynylphosphonates from 1,1-dibromo-1-alkenes has been developed. In general, the best catalyst system for this transformation was found to be Pd(OAc)(2), dppf, H-phosphonate, propylene oxide, DMF, 80 degrees C.
