Abstract

PURPOSE:To provide the subject new compound useful as an antitumor agent and a production intermediate for NCS-C stable to heat and light. CONSTITUTION:A compound of formula I (R<1> is lower alkanoyl; R<2> and R<3> are H or lower alkyl), e.g. 12-(2-alkanoylthioethyl)-5-oxybicyclo[8.3.0]trideca-1,10- diene-3,8-diyne. The compound can be produced by reacting 1,5-dihydroxy-12-(2- alkanoylthioethyl)bicyclo[8.3.0]trideca-10-ene-3,8-diyne compound of formula II with oxalyl chloride in DMSO solvent in the presence of triethylamine. An antitumor antibiotic substance neocartinostatin is known as a therapeutic agent for gastric cancer, pancreatic cancer, acute leukemia, etc., and the substance is composed of a protein segment having a molecular weight of 11,000 and NCS-C having a molecular weight of 659.

13.1 g (0.304 mol) of an OH aqueous solution was added. This two-layer reaction solution was cooled to 10° C. under an argon stream, and 24 ml (0.235 mol) of 30% H2O2 was added dropwise over 95 minutes. The mixture was further stirred at room temperature for 15 minutes, and after confirming the absence of excess hydrogen peroxide using potassium iodide-starch paper, the two layers were separated, and the aqueous layer was washed twice with 80 ml of ether and then concentrated. The residue was dissolved in 600 ml of hexamethylphosphoric acid triamide (HMPA), and 92 ml (0.799 mol) of secBuI was added thereto.
Stirred at room temperature for 88 hours. This was neutralized with saturated sodium bicarbonate solution, 1 liter of ethyl acetate and 1.2 liters of water were added to separate the two layers. Extracted 5 times with 500 ml of ethyl acetate, washed the organic layer once with 500 ml of water and once with saturated saline, dried over magnesium sulfate, filtered, and removed the solvent to obtain 22 kg of silica gel and hexane:ethyl acetate = 2. .28

1) was added dropwise over 1 minute. The mixture was heated with a dryer for several minutes to promote the reaction, and then stirred for 40 minutes until the cloudiness and heat generation ceased, thereby preparing a propargyl Grignard reagent.

Cooled to 80°C. The previously prepared propargyl Grignard reagent was added dropwise to this solution over 70 minutes while stirring vigorously. After stirring for another 2 minutes, add 300ml of water,
Subsequently, 300 ml of saturated ammonium chloride water was added and the temperature was returned to room temperature. The aqueous layer was extracted three times with 150 ml of ether, and the organic layer was combined and washed with 200 ml of saturated brine. After drying with magnesium sulfate, filtration and removal of solvent, an unrefined reddish brown oil was obtained. This reddish-brown oil is 1

After the dropwise addition was completed, the temperature was allowed to rise naturally in a cold bath. After 19.5 hours, TLC showed isobutyl (3-bromo-4-hydroxy-4-(2-propynyl)-2-cyclopentenyl acetate).
A small amount of diisobutylaluminum hydride was confirmed in hexane.

The antibacterial activity against Ococcus luteus ATCC9341 was measured as an index. M. lute
Us was grown in STA medium (manufactured by Nippon Suisan Co., Ltd.) according to a conventional method until the medium reached 3.4 x 105 cells/ml, and 20 ml of this was placed in a No. 2 square Petri dish (14 x 10 cm).
The solution was dispensed and solidified to a thickness of 3 mm and used as a test plate. The compound of the present invention obtained in Example 16 (2
mg/ml) was added, allowed to soak in, and pasted on the above-mentioned assay plate. After spreading the sample onto the assay plate for 3 hours at 4°C, it was incubated overnight at 25°C. The results are shown by measuring the diameter (mm) of the inhibition circle (dia-m (mm
