Title: Gamma-amino alcohols prepn. - from beta-dicarbonyl cpds., and their conversion into azetidine derivs.
Inventor: SECOR HENRY V
IPC: C07D213/38
Filed: 1976-06-25
Abstract: In a novel prodn. of gamma-amino-alcohols, a beta-dicarbonyl cpd. of the formula R1-CO-CR2R3-CO-R4 (I) or R1-CO-CR2R3-CO-OR5 (II) (where R1 is H, alkyl, aryl, or alkylaryl; R2 and R3 are H, alkyl, aryl, alkylaryl or a heteroaromatic or alkylheteroaromatic residue; R4 is H, alkyl, aryl or alkylaryl; and R5 is alkyl) is reacted with an alkoxyamine to give a monoalkoximino intermediate. The intermediate is reduced to the gamma-amino-alcohol. The gamma-amino-alcohol products are cpds. of the formula H2N-CHR1-CR2R3-CHR4-OH (III). Such cpds. in which R2 and R3 are each H, alkyl, aryl, alkylaryl or a heteroaromatic residue and at least one of R2 and R3 is a heteroaromatic residue are claimed as new cpds. Aminoalcohols of formula (III) are useful as intermediates for azetidines, the prodn. of which is claimed. The azetidine derivs, are useful as pesticides active against e.g. spider mites. They are active against both adult and nymph forms of such pests. In an example, ethyl 3-amino-3-(3-pyridyl)propionate is reacted with tosyl chloride, the resulting N-tosyl cpd. is reduced with LiAlH4, the resulting 3-(p-toluenesulphonamido)-3-(3-pyridyl)propanol is reacted with tosyl chloride, and the resulting 3-(p-toluenesulphonamido)-3-(3-pyridyl)-propyl p-toluenesulphonate is cylised to give 2-(3-pyridyl)-N-(p-toluenesulphonyl)-azetidine.

Patent DE-2635456-A1 (DE)
Inventor: RUSZNYAK ANDREAS
IPC: G04G99/00
Filed: 1976-08-04
Abstract: An electronic circuit arrangement designed to store for an indefinite period a signal voltage of predetermined magnitude briefly applied thereto, comprises a main storage capacitor Cs connected via a first semiconductor switch T1 across a supply of unipolar voltage and via a second semiconductor switch T2 across an ancillary storage capacitor Cx, the latter lying in series with a binary capacitor Ci between two conductors M,  PHI 1 across which a clock pulse V PHI 1 is periodically generated. The semiconductor switches are field-effect transistors of the insulated-gate type (IGFETs), the gate of the first IGFET T1 being tied to the junction X between the ancillary storage capacitor Cx and the gate of the binary capacitor Ci; this junction X communicates with the junction S between the two IGFETs and the main storage capacitor Cs in the conductive state of the second IGFET T2 whose gate receives a series of unblocking pulses V PHI 2, lagging behind the clock pulses V PHI 1. The unblocking pulses may be generated at the same cadence as the train of clock pulses, in interleaved relationship therewith; they could also be derived from the junction S between the first IGFET T1 and capacitor Cs by having that junction tied to the gate of the second IGFET T2, the latter thus acting as a diode which conducts after the first IGFET T1 has been turned on to recharge the capacitor Cs. The generator of clock pulses V PHI 1 may serve as the voltage supply for the first IGFET T1 by having one of its conductors,  PHI 1, joined to the channel of that IGFET via a third IGFET T3 connected as a diode.
