isoQUINOLINE DERIVATIVES. PART III

, 1957
In contrast with the earlier observation (Ghosh and Dutta, this Journal, 1955, 32, 17, 755) that treat­ment of (a-acetamido-β-phenyl)-etbylmethyl ketone and of β-phenyl-substituted analogues with POCI3 or conc. H2SO4 leads to the formation of I-methylisoquinoline derivatives, accompanied with dehy­drogenation and deacetylation, (α-scetamido-β-phenyl ...

Transposable Element‐Mediated Structural Variation Drives Flower Colour Diversification in Camellia

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1725-1739, March 2026.
ABSTRACT The role of transposable elements (TEs) in genome evolution and phenotypic diversification in Camellia remains poorly understood. Here, we present an integrated analysis of genome resequencing data from 237 Camellia accessions and 11 de novo genome assemblies representing all major floral colour types.

Open data phylometabolomics reveals turnover‐dominated chemical divergence and clade‐specific physicochemical regimes across angiosperms

The Plant Journal, Volume 125, Issue 6, March 2026.
Significance Statement Using an open, reproducible phylometabolomics pipeline (LOTUS + standardized taxonomy; ~77 000 occurrences), we show that angiosperm chemodiversity diverges primarily by turnover (replacement), not nested accumulation. Despite this dynamism, major clades occupy distinct physicochemical regimes, revealing conserved constraints ...

Synthesis of Pyrrolo[2,1-a]isoquinolines by Multicomponent 1,3-Dipolar Cycloaddition

Molecules, 2013
Pyrrolo[2,1-a]isoquinoline derivatives were synthesized by one-pot three-component reactions starting from isoquinoline, 2-bromoacetophenones and different non-symmetrical acetylenic dipolarophiles using 1,2-epoxypropane as solvent.
