Abstract
Process intensification through continuous flow reactions has increased the production rates of fine chemicals and pharmaceuticals. Catalytic reactions are accelerated through an unconventional and unprecedented use of a high-performance liquid/liquid counter current chromatography system. Product generation is significantly faster than in traditional batch reactors or in segmented flow systems, which is exemplified through stereoselective phase-transfer catalyzed reactions. This methodology also enables the intensification of biocatalysis as demonstrated in high yield esterifications and in the sesquiterpene cyclase-catalyzed synthesis of sesquiterpenes from farnesyl diphosphate as high-value natural products with applications in medicine, agriculture and the fragrance industry. Product release in sesquiterpene synthases is rate limiting due to the hydrophobic nature of sesquiterpenes, but a biphasic system exposed to centrifugal forces allows for highly efficient reactions.

Abstract
In the realm of natural product chemistry, few isolates have risen to the level of fame justifiably accorded to Taxol (1) and its chemical siblings. This report describes the most concise route to date for accessing the highly oxidized members of this family. As representative members of taxanes containing five oxygen atoms, decinnamoyltaxinine E (2) and taxabaccatin III (3), have succumbed to enantioselective total synthesis for the first time in only 18 steps from a simple olefin starting material. The strategy holistically mimics nature's approach (two-phase synthesis) and features a carefully choreographed sequence of stereoselective oxidations and a remarkable redox-isomerization to set the key trans-diol present in 2 and 3. This work lays the critical groundwork necessary to access even higher oxidized taxanes such as 1 in a more practical fashion, thus empowering a medicinal chemistry campaign that is not wedded to semi-synthesis.

Abstract
![]()
Density
functional theory (DFT) calculations with B3LYP and M06
functionals elucidated the reactivities of alkynes and Z/E selectivity of cyclodecatriene products in the
Ni-catalyzed [4 + 4 + 2] cycloadditions of dienes and alkynes. The
Ni-mediated oxidative cyclization of butadienes determines the Z/E selectivity. Only the oxidative cyclization
of one s-cis to one s-trans butadiene
is facile and exergonic, leading to the observed 1Z,4Z,8E-cyclodecatriene product.
The same step with two s-cis or s-trans butadienes is either kinetically or thermodynamically unfavorable,
and the 1Z,4E,8E- and 1Z,4Z,8Z-cyclodecatriene isomers are not observed in experiments. In addition,
the competition between the desired cooligomerization and [2 + 2 +
2] cycloadditions of alkynes depends on the coordination of alkynes.
With either electron-deficient alkynes or alkynes with free hydroxyl
groups, the coordination of alkynes is stronger than that of dienes,
and alkyne trimerization prevails. With alkyl-substituted alkynes,
the generation of alkyne-coordinated nickel complex is much less favorable,
and the [4 + 4 + 2] cycloaddition occurs.
