Abstract: Systems for intelligent automated response to line frequency and voltage disturbances by a central control point communication with a plurality of load control devices. The systems may include a load control device adapted to communicate with one or more energy consuming devices. The load control device may have a load control device firmware adapted to receive and process control directives to change the load of at least one energy consuming device. A central control point may be associated with the building and may be connected to the line power. The central control point may include a circuit adapted to monitor the line power and a central control point firmware adapted to detect the line disturbance. The central control point firmware may be in communication with the load control device firmware and may be adapted to transmit the control directives to the load control device firmware.

Abstract: .alpha.-Amino-.gamma.-butyrolactones (homoserine lactones) are a central structural element in many biologically active compounds. The known syntheses for the preparation of optically active homoserine lactones from D- or L-methionine and D- or L-aspartic acid derivatives have disadvantages. Homoserine lactones I and their salts can be prepared enantioselectively according to the invention by catalytic hydrogenation of aldehydes II ##STR1## where R in the formulae is hydrogen, alkyl, alkenyl, alkynyl, it being possible for the aforementioned three radicals to have hetero atoms in the chain, alkylcarbonyl, alkoxycarbonyl, alkylsulfonyl, benzyl, benzyloxycarbonyl, aryloxycarbonyl or arylsulfonyl, it being possible for the four last-mentioned radicals to be optionally substituted in the aryl moiety.
