The Forward And Backward Rate Constants In Addition To The Activation Energies For R = Allyl And Bu Were Also Determined. However,Only The Rate Constants At 35 Degrees C Were Determined For The Benzyl Compounds With Toluene As The Solvent To Reduce The Reaction Rate. Moreover,The Effects Of The Structures Of The Groups R And The Leaving Groups X On The Reactivity Were Compared. Results In This Study Can Provide Valuable Information For Future Studies Involving The Phase Transfer Catalyzed Displacements. (C) 1996 John Wiley & Sons,Inc.

The invention relates to a new process for the manufacture of alpha -chlorinated chloroformates and, to new alpha -chlorinated chloroformates as new industrial products. The process according to the invention consists of a synthesis, by catalytic phosgenation, of alpha -chlorinated chloroformates of the formula: in which: R represents a substituted or unsubstituted hydrocarbon radical and m represents an integer superior or equal to one, this synthesis consisting in reacting phosgene with the aldehyde R-CHO)m, in the presence of a catalyst which is an organic or inorganic substance which is capable in a medium containing an aldehyde of the formula R-CHO)m, phosgene and, possibly, a solvent, of generating a pair of ions one of which is an halogenide anion and the other is a cation which is sufficiently separated from said halogenide anion so as to give to the latter a nucleophilic power enabling it to react with the function(s) aldehyde of the molecule R-CHO)m.

The disclosed methods are based on the discovery that the reaction of a ylid with an organoborane at a high ylid:borane ratio and high temperature provides for the synthesis of high molecular weight polymers with low polydispersity.
专利号:US-7759520-B2 优先权日:1996-11-27 标 题 :Synthesis of selective androgen receptor modulators 发明人:DALTON JAMES T; MILLER DUANE D; YIN DONGHUA; HE YALI 权利人:UNIV TENNESSEE RES FOUNDATION 摘要:The present invention relates to a synthetic process for the preparation of a novel class of androgen receptor targeting agents (ARTA) which demonstrate androgenic and anabolic activity of a nonsteroidal ligand for the androgen receptor. The agents define a new subclass of compounds which are selective androgen receptor modulators (SARM) which are useful for a) male contraception; b) treatment of a variety of hormone-related conditions, for example conditions associated with Androgen Decline in Aging Male (ADAM), such as fatigue, depression, decreased libido, sexual dysfunction, erectile dysfunction, hypogonadism, osteoporosis, hair loss, anemia, obesity, sarcopenia, osteopenia, osteoporosis, benign prostate hyperplasia, alterations in mood and cognition and prostate cancer; c) treatment of conditions associated with Androgen Decline in Female (ADIF), such as sexual dysfunction, decreased sexual libido, hypogonadism, sarcopenia, osteopenia, osteoporosis, alterations in cognition and mood, depression, anemia, hair loss, obesity, endometriosis, breast cancer, uterine cancer and ovarian cancer; d) treatment and/or prevention of chronic muscular wasting; e) decreasing the incidence of, halting or causing a regression of prostate cancer; f) oral androgen relacement and/or other clinical therpauetic and/or diagnostic areas. The process of the present invention is suitable for large-scale preparation, since all of the steps give rise to highly pure compounds, thus avoiding complicated purification procedures which ultimately lower the yield. Thus the present invention provides methods for the synthesis of non-steroidal agonist compounds, that can be used for industrial large-scale synthesis, and that provide highly pure products in high yield.
