Process for preparation of allyl sulfone derivatives and intermediates for the preparation

The present invention relates to a process for producing an allyl sulfone derivative represented by the formula (3): wherein Ar is an optionally substituted aryl group, and the corrugated line means either one of E/Z geometrical isomers, or a mixture thereof, which is an intermediate for producing vitamin A, which process is characterized by reacting an aryl sulfinic acid or a salt thereof represented by the formula (2): ArSO2M (2) wherein Ar is as defined above, and M is hydrogen atom, sodium atom or potassium atom, with an allyl halide derivative represented by the formula (1): wherein X is a halogen atom, and Ar and the corrugated line are as defined above.

Preparation of (7Z) - and (7Z,11Z) - Vitamin A

An efficient access to (7Z)- and (7Z,11Z)-vitamin A is described. Following the addition of a C6-acetylenic building block to 2,6,6-trimethylcyclohexanone (2), dehydration of the tert. alcohol 3 and formation of the C15-Wittig salt, the (7Z)-geometry was introduced by partial hydrogenation of the triple bond over Raney-nickel. Following Wittig reaction with (E)-2-methyl-4-acetoxy-2-butenal gave a mixture of the title compounds 8 and 9 which could easily be separated.

Electro-organic Reactions. Part 20. Electrogenerated Bases, Ylide Formation, and Wittig Alkene Synthesis

Dicyano(fluoren-9-ylidene)methane (1a), dicyano(2,7-dibromofluoren-9-ylidene)methane (1b), and ethyl 2-cyano-2-fluoren-9-ylideneacetate (1c) may be cathodically reduced in N,N-dimethylforamide to give dianions which efficiently convert phosphonium salts into ylides.The potentials required are sufficiently modest to allow the electrogeneration of the bases in the presence of several phosphonium salts and of several aldehydes to give a convenient method of carrying out the Wittig alkene synthesis.This method has been explored for the synthesis of stilbene, 1,4-diphenylbutadiene, and vitamin A acetate.The basicity of the dianions varies according to the choice of electrolyte cation (Bu4N+ or Li+).The cations also have a marked effect on the stereochemical course of the reaction and, in particular, mixtures of alkenes are obtained in which the cis-isomer predominates in the presence of lithium ion; in the vitamin A acetate synthesis, the 11-cis-isomer constitutes 76percent of the product.The results are consistent with recent hypotheses concerning the mecahnism of the Wittig reaction.
