Aplicação

sec-Butyllithium solution (1.4M in cyclohexane) has been used in the multi-step synthesis of 5-methyl-5,6-dihydrothymidine (5-MDHT) from thymidine. It has also been used in the copper-catalyzed asymmetric allylic alkylation (AAA) of allyl bromides, chlorides, and ethers in the presence of a chiral ligand.

Embalagem

The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.

Although living polymerization methods are widely applicable to organic monomers, their application to inorganic monomers is rare. For the first time, we show that the living poly(methylenephosphine) (PMPn- ) anion can function as a macroinitiator for olefins. Specifically, the phosphaalkene

A series of 6,6-dihalo-2-azabicyclo[3.1.0]hexane and 7,7-dihalo-2-azabicyclo[4.1.0]heptane compounds were prepared by the reaction of dihalocarbene species with N-Boc-2,3-dihydro-1H-pyrroles or -1,2,3,4-tetrahydropyridines. Monochloro substrates were synthesised as well, using a chlorine-to-lithium exchange reaction. The behaviour of several aldehydes and ketones under reductive amination

Silyl triflate precursors to cyclic alkynes and allenes serve as valuable synthetic building blocks. We report a concise and scalable synthetic approach to prepare the silyl triflate precursors to cyclohexyne and 1,2-cyclohexadiene. The strategy involves a retro-Brook rearrangement of an
