Aliphatic Poly(Carbonate)s with Acid Responsive Release Mechanisms for Micellar Anti‐Tumor Drug Delivery

Macromolecular Rapid Communications, Volume 47, Issue 14, 20 July 2026.
Micellar systems based on biodegradable aliphatic polycarbonates and acid‐responsive triggers enhance drug solubility, stability, and tumor‐selective release. This review covers micelles with acid‐cleavable drug linkages and those that disassemble via acid‐sensitive functionalities.

1,3-Dipolar Cycloadditions of Chiral Nitrones [PDF]

, 1989
The asymmetric synthesis of natural products via 1,3-dipolar cycloadditions of chiral nitrones to prochiral olefins has been an area of intense activity over the past decade. The work described in this thesis involves the application of two short, highly

Phospha-Münchnones: Electronic Structures and 1,3-Dipolar Cycloadditions [PDF]

, 2016
The reaction of imines, acid chlorides, PR3, and base generates a new class of 1,3-dipoles: phospha-Münchnones. These 1,3-dipoles can undergo cycloadditions with alkynes followed by loss of phosphine oxides to form pyrroles.
