A novel synthesis of a key intermediate for (+)-biotin from L-aspartic acid

The aldol reaction of an N-Cbz-3-amino-4-butanolide 4, derived from L-aspartic acid, with formaldehyde gave the trans-disubstituted 3-amino-4-butanolide 5 stereoselectively. Following protection of the hydroxyl group of 5, amidation and oxidation provided the beta-substituted L-asparagine derivative 6. The Hofmann rearrangement of 6 with sodium hypochlorite in the presence of sodium hydroxide and subsequent hydrogenation gave the bicyclic lactone 11, which upon dibenzylation and thionation, gave the thiolactone 2, a key intermediate for the synthesis of (+)-biotin (1).

gamma-Hydroxybutenolide Containing Marine Natural Products and Their Synthesis: A Review

gamma-Hydroxybutenolides (gamma-HB) is an important structural core found in many bioactive marine natural products (MNPS). The gamma-HB core containing NPS served as an inspiration to medicinal chemists to undertake designing of the new synthetic strategies to construct gamma-HB core. Subsequently, it further results in the development of novel physiological and therapeutic agents. The most notable example includes manoalides, cacospongionolides, petrosaspongioide M and dysidiolide from marine sponges possessing anti-inflammatory properties. gamma-HB containing MNPS were known to possess various pharmacological properties such as antimicrobial (acantholide B), cytotoxic (acantholide A-E, spongianolide A), inhibitors of secretory phospholipase A2 (cladocorans A and B), BACE inhibitors (ianthellidone G), etc. Moreover, the gamma-HB moiety was explored as anti-fouling agents as well. Owing to their numerous biological activities and attractive molecular structures, there are lots of advances in the synthetic methodology of these compounds. This review gives the account on isolation and biological studies of MNPS with gamma-HB skeleton as a core unit. Furthermore, the synthesis of selective gamma-HB containing bioactive MNPS like manoalide, secomanoalide, cacospongionolides, luffarielloide and dysidiolide were highlighted in the article.

A review of biorefinery separations for bioproduct production via thermocatalytic processing

With technological advancement of thermocatalytic processes for valorizing renewable biomass carbon, development of effective separation technologies for selective recovery of bioproducts from complex reaction media and their purification becomes essential. The high thermal sensitivity of biomass intermediates and their low volatility and high reactivity, along with the use of dilute solutions, make the bioproducts separations energy intensive and expensive. Novel separation techniques, including solvent extraction in biphasic systems and reactive adsorption using zeolite and carbon sorbents, membranes, and chromatography, have been developed. In parallel with experimental efforts, multiscale simulations have been reported for predicting solvent selection and adsorption separation. We discuss various separations that are potentially valuable to future biorefineries and the factors controlling separation performance. Particular emphasis is given to current gaps and opportunities for future development.

A short practical synthesis of 2?-deoxymugineic acid

A short and practical synthesis of 2?-deoxymugineic acid (DMA) has been developed via reductive alkylation with the aldehyde intermediates. No protection of azetidine-2-carboxylic acid was required and the presence of free carboxylic acid function facilitated purification by simple acid and base extractions. Furthermore, the intermediates were conveniently purified by HPLC due to the presence of chromophoric benzyl ester protecting group(s). Hydrogenolysis of the benzyl protecting groups in the final step furnished DMA in overall good yield.
