Advanced Synthesis &Catalysis, Accepted Article.A straightforward synthesis of spirolactones from carbonyls via N‐tosylhydrazones is described. The process consist in the reaction between the N‐tosylhydrazone and ethoxycarbonylethylboronic acid or ethoxycarbonylpropylboronic acid, leading to spiro γ‐butyrolactones or δ‐valerolactones respectively. The transformation takes place by carboborylation of

Pot‐Economical Synthesis of Fluorinated Pyrrolizinone Derivatives
Advanced Synthesis &Catalysis, EarlyView.Abstract A new family of fluorinated dihydropyrrolizinones has been synthesized starting from fluorinated enamino amides and aliphatic conjugated ketones. The reaction comprises a cross metathesis reaction followed by a tandem cycloaromatization/ enamine hydrolysis/ intramolecular Friedel‐Crafts alkylation sequence.

Variety and the evolution of refinery processing [PDF]
Evolutionary theories of economic development stress the role of variety as both a determinant and a result of growth. In this paper we develop a measure of variety, based on Weitzman's maximum likelihood procedure.

Synthesis of Polysubstituted Naphthalenes via Metal‐Free Borylative Cyclization of o‐Alkynylstyrenes
Advanced Synthesis &Catalysis, EarlyView.Abstract A selective, metal‐free method for the synthesis of boron‐functionalized polysubstituted naphthalenes via BCl3‐mediated cyclization of α‐substituted o‐alkynylstyrenes is described. The reaction exhibits broad substrate scope, tolerating various groups such as ethers, sulfides and halogens, and delivers high yields under mild conditions, even ...
