    摘要: A novel process is described for preparation of biotin comprising preparation of substituted 3H, 5H-imidazo[1, 5c]tetrahydro thiazoles by contacting the boron triflouride adduct of an appropriate thiazoline with the metallic derivative of an ester enolate, reducing the ester, hydrolyzing the thiazolidine moiety and hydrolyzing or oxidizing the resultant compound. Intermediates obtained in the preparation of biotin by the above process and alternate procedures for preparing said intermediates are also presented. A novel process for preparation of d-biotin is also given.
