This thesis describes an improvement of the glyoxylate ene reaction by using siamyl glyoxaylate and a development of the novel rearrangement of allyl benzyl ethers. The glyoxylate ene reaction was used as a key reaction in a 8-step synthesis of a Taxol A-ring building block. During the work with the ene reaction it was found that the ene component underwent a rearrangement to give arylbutanals in

A set of pre- and post-storm beach profile data was assembled and the profiles classified into seven different cross-shore morphology change types resulting from overwash. These were crest accumulation, dune/berm translation, dune lowering, dune destruction, barrier accretion, short-term barrier rollover, and barrier destruction. Pre- and post-storm barrier profile sets from recent laboratory expe

The backplane in amulti-board system has a limited wiring capability, which makesadditional backplane Boundary-Scan wiring to link the boards highlycostly. The problem is to access the Boundary-Scan tested boardswith the Boundary- Scan controller at the central board. In thispaper we propose an approach suitable for the Advanced TelecomComputing Architecture standard where we make use of the exist
