Synthesis of β‐N‐Heterocyclic‐Cyclobutane‐Fused Bicyclic γ‐Lactones from 2‐Hydroxycyclobutanone and Carboxamide‐Bearing Wittig Reagents

European Journal of Organic Chemistry, EarlyView.
The reaction of 2‐hydroxycyclobutanone with a Wittig reagent bearing a benzooxazolone moiety results in the formation of a cyclobutane‐fused bicyclic γ‐lactone with the heterocyclic unit located at the bridgehead position. The proposed mechanism involves the transfer of the acyl ylide fragment and an intramolecular Wittig reaction to provide an ...

Total Synthesis of Ectocarpin A

European Journal of Organic Chemistry, EarlyView.
A fully enantioselective total synthesis of ectocarpin A, a new oxylipin, has been achieved in 12 steps starting from tetrahydro‐1H‐cyclopentafuranone. Key steps include the formation of the chiral core, diastereoselective epoxidation, enzymatic desymmetrization of a 1,4‐diol, epimerization, and strategic Wittig and Julia‐Kocienski olefinations to ...

Synthetic Biology‐Based Engineering Living Therapeutics for Antimicrobial Application

Exploration, EarlyView.
This perspective highlights synthetic biology‐driven antibacterial strategies, focusing on three innovative approaches: engineered bacteriophages for precision bacterial targeting, reprogrammed microbes that detect quorum‐sensing signals or metabolites to release antimicrobials, and engineering mammalian cells that recognize pathogen‐associated ...

Self‐Warning and Self‐Repairing Mechanisms in Functional Coatings: A Review

Exploration, EarlyView.
In this paper, we summarize the research progress of self‐warning and self‐repairing coatings in the field of metal corrosion protection as much as possible from the perspective of functional material selection. Meanwhile, the current progress of substituting dual‐functional coatings for single‐functional coatings is also highlighted. ABSTRACT Coatings
