Abstract: In the prodn. of biotin, (A) a 2-formyl-3,4- diaminothiophene (I) is subjected to Wittig reaction with a carboxypropylidene-phosphorane (II); (B) the resulting 5-(3,4-diaminothienyl)-pentenoic or -pentadienoic acid deriv. (III) is hydrogenated in a conventional manner; (C) the protecting groups R1-R4 are removed from the resulting tetrahydrothiophene deriv. (IV) by saponification or hydrogenolysis. and (D) if necessary the intermediately formed diamine deriv. is converted into biotin by reaction with phosgene. In the formulae R1-R4 are H or a usual amino-protecting group removable by acidic or basic hydrolysis or hydrogenolysis; or R1 and R3 together represent a carbonyl group; and R5 is lower alkyl, triarylsilyl or acyl. Biotin (vitamin H) is essential for human nutrition. The hydrogenation steps give an all-cis product, so that racemic biotin is obtd. free from other diastereomers.

Abstract: New 3,4-diamino-thiophene-2-carboxylic acid esters are of formula (I): (where R1-R4 are H or usual amino- protecting gps. removable by acidic or basic hydrolysis or by hydrogenolysis; or R1 and R3 together represent a carbonyl gp.; and R5 is lower alkyl, benzyl, trialkylsilyl or tert-butyl). (I) are useful as intermediates for biotin, pharmaceuticals and dyes. Conversion into biotin is effected by redn. and partial oxidn. to 3,4-diamine-1- formyl- thiophene cpds., Wittig reaction with a phosphorane deriv. to introduce the biotin side-chain, hydrogenation of the prod. and cyclisation with phosgene. Specifically claimed is 3,4-diamino-2- carbomethoxy- thiophene; 3,4-di(2-oxo-imidazolido)-2- carbomethoxy- thiophene; and 3 other cpds.

Abstract: New 3-oxo-4-dimethylaminomethylidene-tetrahydrofurans have formula (I): (where R1 and R2 are H, Me or Et). The use of (I) to prepare 3,4-dioxo-tetrahydrofurans having formula (IV), by oxidn. with singlet-O, is claimed. (I) can be used as aromatising materials and have a malty, bread-like odour, similar to, but weaker than, that of (IV). (IV) are known aroma materials. (I) can be prepd. economically, in good yields, e.g. 80-90%. Conversion to (IV) is quantitative. In an example, 3-oxo-2,5-dimethyl-4-dimethylamino-methylidene tetrahydrofuran was prepd. by stirring 3-oxo-2,5-dimethyl-tetrahydrofuran with either (a) tert. butoxy-bis-(dimethylamino)-methane or (b) N,N-dimethyl-formamide-dimethyl acetal.

Abstract: Prepn. of thiophenes of formula involves (i) dehydrogenation of dihydrothiophenes of formula (II) by means of phosphoric acid chloride or bromide SO2Cl2, SO2Br2, Cl2, Br2, I2, or R10 -CO-N(X)-R9 or (ii) dehydrogenation of disulphido-(3,3')-bis-(dihydrothiophenes) of formula (III): or of dihydrothiophenes of formula (IV) by means of SO2Cl, SO2Br2 or Cl2. In the formula R1 is a gap. (V):- R3-O-, R3-S-, r3-2N-, R3-SO3-, R3-CO-S- or R3-CO-O-; R2 is -CO-OR3, -CN, -CO-NR32 or -CO-R4; R3 and R4 are (cyclo)aliphatic, araliphatic or aromatic gps, and R3 may also be H; R1 and R2 may also together form a gp. R5 is H; R6 is -N-R8, -O-, or -S-; R7 is a (cyclo)aliphatic araliphatic or aromatic gp., or R5 and R7 may form, with the 2 adjacent C atoms, part of an aromatic residue; R8 is H or an aliphatic gp.; R9 is H or -CO-R10-R10 is an (ar)aliphatic or aromatic gp., or 2 R10 gps. may form together a -CO-R11 or -NX-C(R3)2-CO- gp.; R11 is an alkylene gp.; R12 has the same meaning as R1; R13 has the same meaning as R12 or when R12 is (V), R13 may be a gp.: X is Cl or Br; and n = 0 or 1.

Abstract: Prepn. of thiophen carboxylic acids of formula (I) is effected by reaction of a 3-ketothiphan carboxylic acid (II) with a sulphonic acid: R4. SO2Y (III) to give a 3-sulphato deriv. then reacting the product with an alkali metal polysulphide. The resulting cpd. is treated with a sulphuric acid chloride or bromide or with Cl2 to give modified polysulphide which is finally treated with ahalogen and water. In the formula R is CO2R3 or H; R2 is H whe R' is -CO2R3; or R' is -CO2R3 when R' is H; R3 is H or an aliphatic group; X is halo; R4 is an aliphatic or aromatic group; Y is halo, the group OR3 or a group -O3S.R4. Provides simple, more economic process for prodn. of (I) which is intermediate for thiophen-saccharin sweetening agents. A typical cpd. methyl-3-chlorosulphonylthiophen-4-carboxylate, was prepd. by the 4-stage process from methyl 3-hydroxy-dihydrothiophen-4-carboxylate.
