Several syntheses of the previously unknown 1,2-dihydro-3H-pyrrolo[1,2-a]pyrrole-1-carboxylic acid and various 5- and 6-substituted derivatives thereof have been devised. Some of these processes have been extended to the heretofore unreported 5,6,7,8-tetrahydropyrrolo[1,2-a]pyridine-8-carboxylic acid and 5,6,7,8-tetrahydro-9H-pyrrolo[1,2-a]azepine-9-carboxylic acid derivatives.Two new processes were developed for the conversion of pyrroles into the corresponding pyrrol-2-acetic acid esters. Both processes were based on the use of the readily available ethoxalylpyrrole derivatives as the starting material. One sequence involved saponification of the α-keto ester, followed by Wolff–Kishner reduction of the crude α-keto acid salt and subsequent esterification of the acetic acid derivative thus produced. The second synthesis commenced with reduction of the 2-ethoxalpyrrole with sodium borohydride to the α-hydroxy ester, which was further reduced to the acetic acid ester with an equimolar mixture of triphenylphosphine and triphenylphosphine diiodide.

Raising silkworms by using artificial feed is not affected by the seasons and can realize the industrialization of silkworm breeding. The study has been conducted the research for using acetic acid as the material of organic acid in fresh mulberry and KUMGANG medicine stone in which various mineral salts are many contained as the material of inorganic salts in artificial feed. When acetic acid esterfied is added to artificial diet as rate of 3.3%, the setae dispersion within 48h was above 98% and the incentive was 100%. Antiseptic effect on artificial feed has been maintained for 90h since falling the feed. Acetic acid has raised the feeding habit on the 3rd instar larvae as the rate of 118.5% to128.4% and the body weight as the rate of 104.5%. KUMGANG medicine stone of the rate of 1% on artificial feed has promoted the growth and development of young silkworm. In the autumn with bad condition on rearing, KUMGANG medicine stone has been decreased the disease occurrence in larvae and raised the quality and yield of cocoon.

Methyl penicillanate has been synthesized by condensation of D-penicillamine with three different variations of the synthon RO2CCH2CHO, followed by esterification of the resulting 4-carboxythiazolidine-2-acetic acid ester, removal of R, and Mukaiyama ring closure. The conditions for the synthesis of an analogous 4-carboxyoxazolidine-2-acetic acid ester, containing an N-benzoyl protecting group, have been worked out. The condensation of threonine with diethinylketone does not lead directly to a vinylogous oxapenam.

The formation and conversion of primary radicals in the irradiated phosphonic acid ester trichlorphon and some related compounds at 77 °K have been studied by ESR. The irreversible changes of spectra by annealing of the sample demonstrate that the chlorine-containing radical type R-CCl21 formed at room temperature represents a secondary type having a precursor with a short half life in the form of a primary radical of similar structure but different conformation which is stable from 77°K to 245°K. A further radical formed at 77°K in trichlorphon is This type disappears at -60°C. In related compounds (DDVP and the acetic acid ester of trichlorphon) a similar radical CH2OR is induced, which in contrast to trichlorphon is converted into an oxygen radical with g=2,0076 and g= 2,017.

Sainfoin (Onobrychis viciaefolia Scop. ‘Melrose’) seedlings tolerated at 15:1 commercial formulation of the sodium salts of MCPB {4-[(4-chloro-o-tolyl)oxy] butyric acid} and MCPA {[(4-chloro-o-tolyl)oxy] acetic acid} applied at rates up to 2.2 kg/ha in the greenhouse and 3.4 kg/ha in the field. Broadleaf weed control was only fair. Applications of 1.1 kg/ha, 2,4-DB [4-(2,4-dichlorophenoxy)butyric acid] ester caused moderate damage to sainfoin initially, but no reduction in yield. Weed control was fair to good. Higher rates of 2,4-DB caused excessive injury unless a heavy growth of weeds protected the sainfoin from contact with the spray. The use of 2,4-D [(2,4-dichlorophenoxy) acetic acid] amine damaged sainfoin severely, although weed control was fair. Nitrofen (2,4-dichlorophenyl-p-nitrophenyl ether) at 3.4 kg/ha caused spotting on sainfoin leaves with no reduction in growth. Initial weed control was good, but sainfoin seedlings did not suppress new weed growth. Herbicide applications made when sainfoin had 1 to 3 leaves provided the best combination of crop tolerance and weed control.
