Advanced Functional Materials, Volume 36, Issue 75, 17 September 2026.A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Analogs of alicyclic alpha-amino acids: effect of ring size and side chain on tumor accumulation [PDF]
, 1988 We studied the tumor-localizing characteristics of alicyclic alpha-amino acid analogs (a-j) without alpha-hydrogen, because of the selective affinity of synthetic nonmetabolizing amino acids such as 1-aminocyclopentanecarboxylic acid (ACPC) and alpha ...

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis
European Journal of Organic Chemistry, Volume 29, Issue 32, 24 August 2026.In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

Stereoselective synthesis of alicyclic ketones: a hydrogen borrowing approach [PDF]
, 2019 A highly diastereoselective annulation strategy for the synthesis of alicyclic ketones from diols and pentamethylacetophenone is described. This process is mediated by a commercially available iridium(III) catalyst, and provides efficient access to a ...
