Elaboration of 1-benzoyltetrahydroisoquinoline derivatives employing a Pictet-Spengler cyclization with α-chloro-α-phenylthioketones. Synthesis of O-methylvelucryptine
Silveira, Claudio C,Bernardi, Carmem R.,Braga, Antonio L.,Kaufman, Teodoro S.
, p. 8947 - 8950 (2007/10/03)
The reaction of N-tosyl-β-phenethylamines with α-chloro-α-phenylthioketones, leading to 1-benzoyl- and 1-pivaloyl-tetrahydroisoquinolines under modified Pictet-Spengler conditions, is described. The synthesis of O-methylvelucryptine employing this transformation as a key step is reported.
Mono halogenation of β-keto sulfides. Synthesis of β-keto-α-phenylthio p-tolyl sulfones
Fortes,Coimbra
, p. 2039 - 2044 (2007/10/02)
β-Keto-α-phenylthio p-Tolyl sulfones are obtained from β-keto-alkyl phenyl sulfides by halogenation with NCS followed by treatment with sodium p-toluene sulphinate.
REGIOSPECIFIC SYNTHESIS OF α-(PHENYLTHIO)CYCLOALKENONES AND OF α-PHENYL-α-(PHENYLTHIO)KETONES VIA αα-ADDITION OF PHENYLSULPHENYL CHLORIDE TO α-DIAZOKETONES
McKervey, M. Anthony,Ratananukul, Piniti
, p. 117 - 120 (2007/10/02)
Cyclic α-diazoketones react with phenylsulphenyl chloride at room temperature to furnish α-chloro-α-(phenylthio)cycloalkanones which undergo ready dehydrochlorination to α-(phenylthio)cycloalkenones when treated with triethylamine; acyclic, terminal α-diazoketones also furnish α-chloro-α-(phenylthio)adducts which are useful electrophiles in the synthesis of α-phenyl-α-(phenylthio)ketones.
