Abstract

A novel and highly enantioselective synthesis of hydroxyalkynyl esters and ethers through the asymmetric addition of alkynyl esters or ethers to aldehydes promoted by a cyclopropyl amino alcohol based zinc catalyst has been developed. The method afforded a library of new enantioenriched hydroxyalkynol esters and ethers (up to 93% yield; 95% ee), and it was compatible with a broad range of functional groups. Moreover, it could be used in the synthesis of carbon-chain-elongated enantioenriched hydroxyalkynol esters and (2 R ,5 R)-musclide-A1, a cardiotonic potentiating principle from musk.

Abstract

To find debonding defects between aluminum panel and foam core in components, a sample was designed and manufactured, in which there were a few debonding defects designed. Signals of debonding defects in the sample was analyzed and used to be compared with those of suspicious areas in the component. Some areas in the component were dissected to prove results. Results of infrared thermographic non-destructive testing of the component before and after load test were compared. Influence factors of defect identification were analyzed, such as defect size, defect thickness, defect depth, curve surface of component, black paint thickness and uniformity. A conclusion was made that infrared thermographic non-destructive testing was suited to test debonding defects in that kind of structure.
