- the hydroxyl-protecting group is trialkylsilyl, more preferably the protecting group is triethylsilyl.
- P is a protecting group other than triethylsilyl
- deprotection methods known in the art can be used (see T.W. Greene and P.G.M. Wuts, Protective Groups in Organic Synthesis, John Wiley & Sons, Inc., New York, 1991, pp.10- 142).
- Reduction of the azido group and subsequent cyclization of a compound of formula V with a reducing agent, such as a triaryl- or trialkylphosphine provides a compound of formula VI, where R,. 5 are methyl and R ⁇ ; is 2-methyl-4- thiazolyl.
- a compound of formula V, where P, is an hydroxyl-protecting group and R 8 is alkyl, substituted alkyl, aryl, or substituted aryl can be converted to an alkyl-, a substituted alkyl-, an aryl-, or a substituted arylsulfonate ester VII by treatment with an alkyl-, a substituted alkyl-, an aryl-, or a substituted arylsulfonyl chloride.
- Reduction of the azido group and subsequent cyclization of a compound of formula VII using a reducing agent such as a triaryl- or trialkylphosphine provides a compound of the invention such as formula VI (where R,.
- azide reducing agents are well known in the art including, but not limited to, hydrogen, Lindlar's catalyst (Pd, CaCO 3 /Pb), tri-n-butyltin hydride, stannous chloride, hydrogen sulfide, and 1,3-propanedithiol.
- a compound of formula III where P, is a hydroxyl-protecting group can be converted to a compound of formula VIII where X is a halogen by treatment with, for example, triphenylphosphine and a carbon tetrahalide.
- X is a halogen
- Alternative reagents for the conversion of a hydroxyl group to a halogen are well known in the art, such as thionyl chloride or phosphorous tribromide (see R.C. Larock, Comprehensive Organic Transformations, VCH Publishers, Inc., New York, 1989, pp. 352-359).
- Reduction of the azido group and subsequent cyclization of a compound of formula VIII using a reducing agent such as a triaryl- or trialkylphosphine provides a compound of the invention such as VI (where R,. 5 are methyl and R e is 2-methyl-4- thiazolyl).
- a reducing agent such as a triaryl- or trialkylphosphine
- Other azide reducing agents are well known in the art including, but not limited to, hydrogen, Lindlar's catalyst (Pd, CaCO 3 /Pb), tri-n-butyltin hydride, stannous chloride, hydrogen sulfide, and 1,3-propanedithiol.
- Et 3 SiCl 25 ml, 149 mmol was added to Epothilone A (10.39 g, 21 mmol), NN-diisopropylethylamine (55 mL, 315 mmol), and imidazole (7.15 g, 105 mmol) in DMF (75 mL) at 25 °C.
- the reaction mixture was heated at 55°C for 6.5 hours and concentrated in vacuo.
- the residue was then diluted with CH 2 C1 2 (100 mL) and the organic extracts were washed with ⁇ aHCO 3 (30 mL), dried over Na 2 SO 4 and concentrated in vacuo.
