Efficient method for the synthesis of 1,2,3,8-tetrahydroindeno[2,1-b]phospholes and their derivatives

An efficient method for the synthesis of 1,2,3,8-tetrahydroindeno[2,1-6]phospholes was developed. The method is based on the direct reduction of the corresponding quasiphosphonium salts with LiA1H4.

Isomerization Processes of Electronically Excited Stilbene and Diphenylbutadiene in Liquids: Are They One-Dimensional?

Various "stiff" diphenylbutadienes with the phenyls held rigid by saturated chains of 2-4 carbons connecting the 2-position of phenyl to the polyene unit have been prepared, and their photophysics explored.The synthesis entailed a combination of Wittig re

SYNTHESIS OF 1,2-DIHYDRO-1-PHENYLINDENOPHOSPHOLANE AS A POTENTIAL PRECURSOR OF A PHOSPHAPENTALENYL ANION

3-Vinyl-1H-indene was employed for the first time as a diene in the McCormack cycloaddition with phenylphosphonous dibromide.The adduct was heated to rearrange the double bond, and on hydrolysis there was obtained 1,2,3,8-tetrahydro-1-phenylindenop

Synthetic Studies directed towards Complex Diterpenoids. Part 15. Synthesis and Stereochemistry of the Catalytic Reduction of Δ4b(5)-Gibbenes and Related Compounds

The synthesis of, and substituent effect in the stereoselectivity of catalytic hydrogenation of, a series of methyl- or methoxy-substituted (+/-)-4b,9-cyclogibba-1(10a),2,4-trien-8-ones (1a-g) and (+/-)-gibba-1(10a),2,4,4b(5)-tetraen-8-ones (2a-g) are described, which lead to stereocontrolled syntheses of the respective C-4b epimeric gibbanes (3a-g) and (4a-g).The key intermediate tetrahydrofluorene-2-carboxylic acids (10a-g), prepared by cycloaddition reactions, are converted into the corresponding α-diazomethyl ketones (12a-g) which are subjected to intramolecular oxo-carbenoid addition or perchloric acid- trifluoroacetic acid-catalysed cyclisation leading to the cyclopropyl ketones (1a-g) and the Δ4b(5)-gibbenes (2a-g), respectively.
