Abstract

Previously unknown dispiropyrrolidines were synthesized by 1,3-dipolar cycloaddition of azomethine ylide to 3-arylmethylidene-3Н-furan-2-ones. The cycloaddition reaction was demonstrated to proceed diastereoselectively through an endo-transition state. Alternative transition states for the reaction are discussed.

Abstract

A structural health monitoring system based on optical sensors has been developed and installed on the indoor soccer arena "Zarya" in Novosibirsk. The system integrates 119 fiber optic sensors: 85 strain, 32 temperature and 2 displacement sensors. In addition, total station is used for measuring displacement in 45 control points. All of the constituents of the supporting structure are subjects for monitoring: long-span frames with under floor ties, connections, purlins and foundation.
