摘要:A process for the production of disubstituted propionic acid derivatives which are intermediates in the synthesis of α-arylpropionic acids such as naproxen, involves the reaction of a naphthalene derivative such as 2-methoxynaphthalene, with an alkylating agent such as an alkyl pyruvate in the presence of a catalyst, and then dehydrating and hydrogenolising, or directly hydrogenolising, or derivatising and then hydrogenolising the product thereof, to produce the desired compound.

摘要:Cis or trans 2-(1-acyl-3-vinyl-4-piperidine)acetic acid esters and cis or trans 3-(1-acyl-3-vinyl-4-piperidine)propionic acid esters, antipodes and racemates thereof, are prepared, inter alia, from the corresponding cis or trans 2- or 3[1-acyl-3-(2-chloroethyl)-4-piperidine]acetic or propionic acid esters, respectively. The cis or trans 2- or 3-(1-acyl-3-vinyl-4-piperidine)acetic or propionic acid esters are useful as intermediates for the synthesis of quinine and quinidine and analogs and stereoisomers thereof.

摘要:CIS OR TRANS 2-(1-ACYL-3-VINYL-4-PIPERIDINE)ACETIC ACID ESTERS AND CIS OR TRANS 3-(1-ACYL-3-VINYL-4-PIPERIDINE)PROPIONIC ACID ESTERS, ANTIPODES AND RACEMATES THEREOF, ARE PREPARED, INTER ALIA, FROM THE CORRESPONDING CIS OR TRANS 2OR 3-1 1-ACYL-3-(2-CHLOROETHYL)-4-PIPERIDINE! ACETIC OR PROPIONIC ACID ESTERS, RESPECTIVELY. THE CIS OR TRANS 2- OR 3-(1ACYCL-3-VINYL-4-PIPERIDINE)ACETIC OR PROPIONIC ACID ESTERS ARE USEFUL AS INTERMEDIATES FOR THE SYNTHESIS OF QUININE AND QUINIDINE AND ANALOGS AND STEROISOMERS THEREOF.
