Bu3SnH

The introduction of the BDT group proceeds under these rather neutral conditions, and this may prove advantageous for acid-sensitive substrates. The BDT group can also be reduced with Raney nickel to a methyl group or with Bu3SnH to a 2-[(methylthio)phenylthio]methyl ether (MTPM ether)... [Pg.67]

Pd(Ph3P)2Cl2, Bu3SnH, P-NO2C6H4OH, CH2CI2, 70-100% yield. This... [Pg.331]

These esters can be deoxygenated with Bu3SnH or, as in the preceding example, with LiAlH4. ... [Pg.189]

Cleavage occurs by prior conversion to the ethylidene acetal with RaNi or Bu3SnH and then the normal acid hydrolysis. The trichloro acetal is cleaved by reduction (H2, Raney Ni, 50% NaOH, EtOH, 15 min). The trichloro acetal can probably be cleaved with Zn/AcOH [cf. ROCH(R )OCH2CCl3, cleaved by Zn/AcOH, AcONa, 20°, 3 h, 90% yield. ... [Pg.206]

Pd(Ph3P)2Cl2(Bu3SnH, benzene) or cobalt carbonyl. The palladium method cleaves allyl esters, propargyl phosphates, and propargyl carbamates as well. [Pg.413]

Bu3SnH, AIBN, PhH, 3 h. A, >72% yield. The thiol is released as a stannyl sulfide that was used directly in a glycosylation. " ... [Pg.459]

Pd(Ph3P)4 and Bu3SnH convert the Alloc group to other amine derivatives when electrophiles such as (B0C)20, AcCl, TsCl, or succinic anhydride are added. Hydrolysis of the stannyl carbamate with acetic acid gives the free amine. [Pg.528]

PdCl2(Ph3P)2, Bu3SnH ClB(OR)2, then aqueous hydrolysis. ... [Pg.672]

Diastereoseleetive 6-exo-trig radieal eyelization of (-)-perhydro-l,3-benzoxazines 69, 71, 74 with Bu3SnH and AIBN gave a diastereomerie mixture of perhydropyrido[2,l-Z)][l,3]-benzoxazines 39, 70, and 72, 73, and 40, 75, respeetively (00TA2809). [Pg.187]
