Diglycerides of Natural Phenols and Organic Acids for Enhanced Biological Activities

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Diglycerides of natural organic acids and phenols were synthesized regio‐selectively. Diglycerides are structurally similar to cell membranes and are expected to exhibit cell affinity and permeability. The flexible glycerol linkers allow the diglycerides to exhibit not only the physiological activities of each constituent organic acid but also the ...

4,6‐O‐Phenylboronic Ester Protection for 1,2‐cis‐α‐Selective Glucosylation

open access: yesAsian Journal of Organic Chemistry, EarlyView.
The 4,6‐O‐phenylboronic ester protection for 1,2‐cis‐α‐selective glucosylation, previously reported by the Crich group, was revisited and the stereodirecting effect of the cyclic protecting group was unveiled. 4,6‐O‐Phenylboronic ester‐protected glucosyl and 2‐azido‐2‐deoxyglucosyl donors exhibited higher α‐selectivity of the glucosylation than the ...

Tuning Antiaromaticity Through Meso‐Substituent Orientation in Core‐Modified Isophlorins

open access: yesAsian Journal of Organic Chemistry, EarlyView.
The antiaromaticity of dithiadioxaisophlorins is controlled by the steric bulkiness of meso‐substituents through their tilt angle relative to the macrocycle. Bulkier substituents maintain larger angles, preserving stronger antiaromaticity, while smaller groups facilitate π‐conjugation with the macrocycle, diminishing antiaromaticity.

Synthesis of Crosslinked Biopolyesters Catalyzed by Natural Amino Acids

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Highly crosslinked bio‐polyesters were synthesized via the ROCOP reaction between epoxidized sunflower oil and biobased cyclic anhydrides. The resulting materials were comprehensively characterized by FT‐IR, TGA, and DSC. A cross‐linked network in the bio‐based polymers has been confirmed by dynamic mechanical analysis.
