(Chemical Equation Presented) Carbohydrates are an omnipresent class of highly oxygenated natural products. Due to their wide spectra of biological activities, they have been in the center of synthetic organic chemistry for more than 130 years. During the past 50 years non-natural carbohydrates attracted the interest of various chemists in the fields of organic, biological, and medical chemistry. Especially desoxygenated sugars proved to be an important class of compounds. Up to date, most non-natural analogues are synthesized starting from natural, enantiomerically pure carbohydrates in multistep synthesis. In this report, we present a synthetic strategy that allows the selective modular synthesis of natural and non-natural carbohydrates within five synthetic steps starting from readily available starting materials. Due to a sequential introduction of O-or N-functionalities, a regioselective protection of each new functional group is possible. The key step in the carbohydrate synthesis is a RuO4-catalyzed oxidative eyclization via a pH-dependent dehydrogenation-dihydroxylation-cyclization or an oxidative fragmentation-cyclization, leading to highly substituted new carbohydrates, in which each functional group is orthogonally protected and accessible for further synthetic operations.

(Chemical Equation Presented) Metathesis to the rescue: Although counterintuitive at first sight, application of ring-closing metathesis (RCM) to a cyclization precursor containing 10 double bonds has led to the selective and high-yielding formation of the macrocyclic core of iejimalide B, a potent cytotoxic agent of marine origin. In contrast, a macrolactonization approach failed to afford this intricate target.

Lipid mediators have attracted great interest from scientists within the chemical, medicinal, and pharmaceutical research community. One such example is leukotriene B4 which has been the subject of many pharmacological studies. Herein, we report a convergent and stereoselective synthesis of this potent lipid mediator in 5% yield over 10 steps in the longest linear sequence from commercial starting materials. The key steps were a stereocontrolled acetate-aldol reaction with Nagao’s chiral auxiliary and a Z-selective Boland reduction. All spectroscopic data were in agreement with those previously reported.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Formula: C4H6O3. Introducing a new discovery about 52079-23-9, Name is (S)-(-)-alpha-Hydroxy-gamma-butyrolactone

To clarify the absolute configurations of antafumicins A and B, which are antifungal substances from Aspergillus niger NH-401, the total synthesis of (2S)-antafumicins was accomplished by starting from (S)-malic acid in 12 steps. Based upon the physicochemical data of the synthetic samples, the absolute configurations of naturally occurring antafumicins A and B were determined as (2R,4S)- and (2R,4R)-4-(3-acetyl-2,6-dihydroxyphenyl)-2-methoxy-4-butanolide, respectively.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C4H6O3, you can also check out more blogs about52079-23-9

The homochiral 1,3-dioxanes 8a-e with a 2-bromophenyl substituent in position 2 and an electrophilic group in position 4 were stereo- and regioselectively prepared from the (S)-malic acid derivatives 6a, 6b, 11, and 14. Attempts to prepare the tricycles 5a-c by connecting the 2-phenyl substituent with the electrophilic groups in position 4 of 8a-e in a Parham cyclization across the 1,3-dioxane ring failed. The synthesis of the tricyclic title ketone 5a succeeded, however, by addition of the lithiated benzaldehyde acetal 7c to the protected alpha-hydroxylactone 10b and subsequent treatment of the intermediate ketone 23 with acid. The acid hydrolysis of the alcohol 26, which was obtained by addition of 7c to the protected dihydroxy aldehyde 25b, followed by oxidation of the resulting alcohols 27 a and b represent a second possibility for the preparation of the tricyclic ketone 5a.
