Novasep has the capabilities and experience for multi-step synthesis and purification from hundreds of grams to thousands of tons. We have a unique know-how for conducting certain demanding reactions used in organic synthesis that yield pure organic compounds in a cost-effective and time efficient manner:
- Cryogenic reactions
- Friedel-Crafts reactions
- Micro-reaction technology
- Transition metal-catalyzed reactions
- Hydrogenation reactions
- Halogenation reactions
- Heterocyclic chemistry
- Mitsunobu reactions
- Biocatalyzed and chemoenzymatic reactions
- And more organic synthesis reactions
We pioneered low temperature reactions at industrial scale for more than 30 years and are equipped for -80 °C reactions at industrial scale.
Ideal to improve selectivity or to use highly reactive compounds such has organolithium reagents, we have can perform cryogenic reactions at pilot-scale (up to 700L) and at industrial-scale (up to 6,000L). We also developed a unique set of two large-scale reactors (3,000 L and 4,000 L) in series for coupling two low temperature reactions.
- This expertise enables us to easily perform and scale up the following reactions:
- Halogen-metal exchange (e.g. Li)
- Li, Na metal reduction
- Selective deprotonation and subsequent stereoselective / regioselective/ chemoselective reactions
- Stereoselective / regioselective/ chemoselective reductions (e.g. ketones, imines, esters)
- Asymmetric reactions (e.g. Michael addition)
- Selective Friedel-Crafts acylation (e.g. with oxalylchloride)
We have the world’s largest cGMP capacity for Friedel-Crafts acylation, alkylation and hydroalkylation with a 6,000 L reactor and more than 30 tons of AlCl3 storage.
We reduce the environmental impact of Friedel-Crafts reactions by supplying the aluminum hydroxide by-product that we generate to water treatment companies.
We are highly active in developing reactions based on micro-reactor technology, especially for energetic or safety critical reactions such as glycerine nitration.
We master catalyzed C-C and C-N cross coupling reactions such as Suzuki, Heck, Sonogashira, and Buchwald reactions from pilot to industrial scale.
Our ability to prepare aryl and vinyl triflates, chlorides and bromides as well as boronic acid derivatives in-house, gives us access to a wide selection of substrates at low cost for transition metal-catalyzed cross coupling reactions.
In addition, our ability to handle carbon monoxide from gram to hundreds of kilogram scale gives us access to a Pd-catalyzed carbonylation reactions.
We are equipped with large-scale hydrogenation capabilities that can be used in both asymmetric and standard version, combined with H-cube screening technology in order to quickly identify the best hydrogenation conditions.
Our production capabilities include 2 x 1,500 L; 3,000 L; 2 x 6,000 L and 8,000 L reactors for hydrogenation reactions at up to 20 bar.
We are equipped with extensive capabilities for bromination and chlorination reactions. We can use up to 10 MT of bromine in our 6,000 L and 4,000 L dedicated reaction vessel.
We are also experts in using Cl2, PCl5, POCl3 and SOCl2 to produce tons of chlorinated compounds in our 4,000 L vessel dedicated to chlorination reactions.
Thanks to these large-scale capabilities, we manufacture various organic halides that can be used as starting material for the other key reactions we master, such as organometallic chemistry, transition metal-catalysed reactions, etc.
We have extensive experience in producing and using several organometallic c
