Chemoenzymatic reaction cascades can provide access to chiral compounds from low-cost starting materials in one pot. Here we describe one-pot asymmetric routes to tetrahydroisoquinoline alkaloids (THIAs) using the Pictet-Spenglerase norcoclaurine synthase (NCS) followed by a cyclisation, to give alkaloids with two new heterocyclic rings. These reactions operated with a high atom economy to gene...

Benzyl ether protected polyhydroxylated alkene compounds containing allylic alcohol, ether or ester functionality undergo a stereospecific cyclisation reaction upon treatment with TFA-acetonitrile-toluene with inversion of configuration at the allylic position and loss of a benzyl ether to give tetrahydrofurans.

The flying ad-hoc networks (FANET) are utilized in the various types of applications, such as weather, military, information retrieval, geographic information systems (GIS), surveillance of disaster hit area, etc. The groups of unmanned aerial vehicles, also called flying nodes or crafts, are used for such applications. The flying nodes or crafts, when take the flight, need to consider multiple...

Traditionally, craft activities have provided a tasteful introduction to mathematics for children: through the building of paper polyhedra, or the creation of patterns in string, children have often come to appreciate profound mathematical ideas. The next decade, however, is likely to see a tremendous expansion of accessible, powerful technology that will (or at least could) radically reshape a...
