Microwave assisted synthesis and anti microbial activity of 2,2-dimethyl chromenes
Suresh Babu,China Raju,Praveen,Hara Kishore,Suryanarayana Murty,Madhusudana Rao
, p. 519 - 526 (2003)
2,2-Dimethyl chromenes (1b-9b) were prepared from corresponding propargyl ethers (1a-9a) under microwave conditions in high yields and anti microbial activity of compounds (6b & 7b) is reported.

It was experimentally demonstrated that microscopic friction between a reactant molecule and the surrounding solvent during a unimolecular structural change increased with increasing bulkiness of substituents and it is suggested that this dependence can be used to identify a moving molecular moiety in the reactant inside of a solvation shell.
A new application of high-viscosity kinetics. An attempt to identify a site of solvent reorganizations around a reactant

Thermal fading of a colored species photochemically generated from so-called chromenes was kinetically studied in highly viscous media. The reaction was retarded by an increase in viscosity at viscosities higher than 102 Pas. We propose to use substituent dependence of this retarding effect as a tool to identify the main site of solvent reorganizations around the reactant molecule in the activation step.
Ligand-controlled regiodivergent π-allyl palladium catalysis enables a switch between [3+2] and [3+3] cycloadditions

Reported herein is the use of ligands to tune the regioselectivity and reactivity of palladium-catalyzed [3+2] and [3+3] cycloadditions. Diverse synthesis with vinylethylene carbonates (VECs) as well as free naphthols has been explored to construct four different valuable polycyclic frameworks in a broad substrate scope.
Synthesis of diverse indene derivatives from 1-diazonaphthalen-2(1 H)-ones via thermal cascade reactions
Somai Magar, Krishna Bahadur,Lee, Yong Rok
supporting information, p. 4288 - 4291 (2013/09/24)
A sequential Wolff rearrangement of 1-diazonaphthalen-2(1H)-ones followed by trapping of the ketene intermediate with primary and aromatic amines or alcohols and phenols in the presence of various aldehydes generates 1H-indene-3-carboxamides or 1H-indene-3-carboxylates. This constitutes an unprecedented three-component coupling reaction that allows for the synthesis of functionalized indene derivatives under catalyst-free thermal conditions.
